I played through them relatively recently and they're still pretty slow. Admittidly, a lot of this isn't just on the attack animations (though that's a big thing), but also the hit animations and just myriad other things that all add up to a slow experience.You're talking about Colloseum compared to X/Y right because I'm pretty sure Colloseum/XD is not that much slower then the other Pokeman games. And I think it might be a little faster then gen 4 but then again that isn't much of an accomplishment.
Whatever the case I just checked out some X footage again and goddamn it IS fast. Thank god. Gamespeed is actually something that is pretty important to me...........lol. Just watch. It'll be all fast in battles and then just like in Black and White the menus are irritatingly slow for some reason. Count on it.
See? See? Ehhhh?
Wish we saw them mess with the bag & menus a little, though. Probably too many spoilers in the key item pocket though
