My feelings on The Demon Rush
Okay, everyone needs to read Breakdown's post, but if you still don't get it stop suggesting stuff you know is obscure/bad marathon choice and has no chance of making it. 
Like Breakdown said, if you don't think you know anything that is marathon material, you have time to learn some games.
Cyghfer: I think it's worth doing Kirby's Avalanche once. Also, you know you can take a Chinatown bus down to DC, right? It's one dollar if you reserve way in advance. I'd actually rather have you work on alttp, since you're already focusing on it. AFAIK, you haven't even touched DKC2.
Mecha Richter: What rom said about a Richter run. Good idea, but you'd have to get a time much better than 12 minutes for me to even consider a run. You have plenty of time to practice
Molotov: Yeah, I didn't think the Shinobi stuff was worth doing last year, but I realize there were some requests for it, and it's not too long so it's worth doing. Hmm, if you don't want to God Hand, that's up to you. I understand what you mean, you did do a really good job during JRDQ. Whether you do Chaos Theory is up to you.
I didn't include Shinobi PS2 because I thought it might be a little on the not popular enough side, but I love the game and it would be an awesome watch if done well, so I'd probably allow it if someone could do an awesome job at it. I know J has expressed interest in practicing this game.
Kirby's Dream Land: It's certainly not a bad add, if nothing else.
Aftermath: I know Breakdown already talked to you about Flash games, and I have to agree with him, not really worth doing, even though some are really good watches and fun (like The Company of Myself). I think out of that list I could possibly give you PoR. I don't know how OoE NG+ works, but if it involves using a form of movement that's not only ridiculously fast but destroys everything, then people might gripe a bit. :-/
The other stuff I'm not really sold on, I know Gauntlet Legends was popular back in the day, but is it really a good watch?
Withhelde: I can give you Kid Chameleon in that list. You already went too far niche at King's Field.
UraniumAnchor: I can definitely give you Blaster Master, and I think Prince of Persia is likely worth doing if you can run it consistently.
Cool Spot is a no, and I don't think Blaster Master 2 is a really fun bad game to watch? I don't think ear bleeding counts.
Dead Space is a maybe. I know it's a popular game, and it might be entertaining, but I don't know enough about it.
Sir VG: I can give you Amazing Mirror in that list. However, I want all players of the game to be well-practiced, and I want some of the co-op practice to happen before we all meet up at AGDQ. Please don't list stuff you know has almost no chance of making it.
FF7 Team Relay: I think this could be a big disaster if too many people get in on this. Only 2 or 3 people max, IMO. And they better be updating me with how practice is going. In fact, I'm not entirely sold on this being a good idea in the first place, because each player needs to make sure their section roughly matches up with the previous and next section for practice.
DJS: I still think GTA games are a bad idea, sorry.
Skullboy: Dynamite Headdy is already being done at SGDQ. I like the game a lot, but I'm not entirely sold it's worth it doing the game for AGDQ, especially since scheduling is going to be ridiculously tight as is. Contra Hard Corps low% is really tedious and boring, IMO. And Knuckles Chaotix is a 32x game, nuff said.
ZakkyDraggy: I love Metal Combat, but you and I both know it has no chance. Strider is a nice add, it's a short arcade classic.
Trio the Punch would be hilarious. Could be casual race of the year!
Tigger77: Glad you're understanding about Link's Awakening.
Lag.Com: That's awesome you're willing to do Quake. It's nice to see a marathon finally getting the game that started it all for SDA. Oblivion is a good replacement for Morrowind. Magicka sounds good (I really need to finish that game). I guess Peggle is Thexder Neo status, and I know Ultima Underworld is a revered classic among PC gamers, but I'm not sure it's the best choice. I don't know how entertaining it would be, or how long it is. BTW, I'm fine if you do stuff on dosbox as long as the game is worth doing.
Mike89: I can easily give you all of the Sonic stuff you suggested. Sorry about Colors, but a lot of people do like that game so yeah it's probably getting in.
As for the other stuff, you make a good point about RKA, doing a hard marathon run might require too many conservative strats to make it worth doing for a marathon. Pokemon Blue is obviously worth doing, and I don't mind if you save a bit here and there to account for luck. I'm sorry, but I don't think Splosion Man is worth doing, it's a great game, but like you said, it's probably too long for what it is.
Zyre: Out of that list, Timesplitters 2 is the best suggestion. I don't know about Future Perfect so maybe that's also a good suggestion, but you need to pick one game or the other.
About Gunstar Heroes, it has nothing to do with how many games I have. I can pick this game up in a day or two (that's not even an exaggeration), and it's a zero-effort game for me, but I don't think it's worth doing again. I'm bored of the game, and it doesn't really get much of a response anyway (from chat or donations), so I'd rather just give it up.
Guardian Heroes might be worth it, kinda unlikely though. Maybe we can do a Treasure Block during another marathon or AGDQ 2013?
Breakdown: Thank you for that post.
Gearstrike: Repping the awful games, nice.
Andrewg: If you can't practice a game, you don't get to play it. We all saw what happened when you couldn't practice your games, let's not repeat that again.
qubit/TheEnglishman: We need someone willing to play the game first, so I'll worry about it only if someone actually offers to play the game. FFS, if someone suggested Heaven or Hell I would kick them in the nuts.
Cosmo: Well if you come I can give you those games. Also, you get jokes. <_<
Pootrain: Sounds good, I'm not entirely sure about Limbo, so I'll have to see how it does during SGDQ.
Gragle_dump: I'm not really sold on Sunshine since that's the 3d mario that gets a lot of hate.
Dr. Mario: YES!! I'm so glad not to see the game again.
Satoryu: X8 is a no. It's more well liked than 5-7, but it still has a really mixed response from fans.
If Sayuri is the only way to run HCU, then fuck HCU. It's probably not even worth doing even if character donations are involved. I know that Other M suggestion is a joke, but seriously don't waste my time with suggestions like that. :-/
No More Heroes? I know it's a cult classic, so it might be worth doing. I have no idea if it's a good watch though.
Bomberman 64: It probably is the best bomberman for a marathon, but that's saying we should have a bomberman game for a marathon, and I'm not really convinced we need one.
Zenic: You are not helping. Don't throw out unfocused lists of games.
Footbigmike: Scott Pilgrim has been suggested to me as a Castle Crashers replacement, but the big problem is no way to practice online.
Also, I'm going to update the main topic with some of the better suggestions I've received since this topic was made. Also, I forgot to include TMNT4 co-op in that list of games I made.
Phew, that was a long post.
