I actually don't understand why PvP or at least 4 players coop aren't a higher priority...I'd rather play with my friends than have the pokégear or a new area or smt. Why's nillz or anybody else of the development team working on this

?
because the game runs like crap and we have a community determined to mod the game and a barely functional map editor i'm busy
i don't know why nils hasnt done it but to be frank, not everyone's a big battling fan. what is a priority for you won't be a priority for everyone else. like, we're getting language support and content packs this week because i cared enough to make them happen. maybe you don't care about content packs? maybe you think the time could have been better spent on something else, but basically the point im trying to make is this stuff only happens if someone wants it to happen. we both want more multiplayer stuff but when you also want a bunch of other things it goes a little down the list.
all this coop, trading and battling multiplayer stuff is dear to my heart so it'll get attention from me eventually if nils doesn't get around to it.
we are very, very aware that we are not catering to the multiplayer crowd at all right now, and it's sad to tell people there's nothing to do. but all the stuff we're setting up makes implementing more multiplayer stuff easier.
