I agree with xddbzfan869, you should join the discord. A lot of the runners of this game/category are probably not looking at forums, so you'll have a better idea of what people have in mind by discussing it in there instead.
YOU'RE COOL I LOVE QUEBEC I LOVE WITHERMIN I LOVE BACON!!!!!!!!!!!!!!
No, actually we still use RTA as default, the precision of time is better with it. Plus, IGT doesn't count the HUB Movement, and also the rest of the game. In fact, IGT would only be counting as default if the '' Everything '' of the game was count internally. So, yes, the version matters a lot if you want a good place on the boards... Hope that answers your question :3
What do you mean ?
If you just bought the game that you already had before and lost your saves because of the Xbox360 and you want to do a run starting with a new file, what do you have to do ?
Yeah, already has been done by some people and there's a good route for it, and it's not 100%, it's All Snags. In theory, 100% would be every single thing in the game.
