Graphics aside, do you like the game play changes we've seen so far in Arceus?

Personally, yes. I'm a little nervous about no trainer battles but I'm not convinced that will actually be the case I think there's a strong chance you end up fighting the members of galaxy team. I don't really give a shit about no online since I never really used it anyways but it is weird to remove and I would like to see competitive battles with the new system, showdown will probably find some way to add it.
