Quote from Gaël:
GTA SA 100% according to the ingame counter doesn't include Unique Stunt Jumps, Burglaries, Triathlons and Girlfriends. Does that mean that if someone goes through the whole process of lossless recording, encoding then submitting a 100% run that only get 100% according to the game it will be rejected because it isn't "doing everything important"?
GTA V 100% skip even more stuff.
GTA V 100% skip even more stuff.
According to the logic presented (in-game counters used if accurate, ignored if not) the run would be fine, assuming it does all the things that normally count towards the percentage. This would go for any game, including SA and V.
On the matter as a whole though, I agree that duping to 100% is questionable and am inclined to say that for Vice City this wouldn't justify a new category on the game page. Though in a more general sense I could definitely justify "fake" 100% runs making it in on a game-by-game basis, I don't think many games would be able to justify the category as more than just something fun to do for a change (read: arbitrary).
For the record, I know Vice City quite well but didn't offer to verify this run because I haven't kept up with developments in speedrunning the game and expected quite a few people who had to offer. I probably should have, but that's water under the bridge.
