No. I only want improved graphics, richer story and more customization.
Basically Pokemon games are already violent with a lot of censure. Team Rocket, kidnapping, taking over a city, giants fighting over land and ocean, guy trying to take over the world and whatnot, Hypno scaring little girls in the woods, ghosts, haunted houses, shipwrecks, killing pokemon (marowak etc)...see where Im going with this.
Really the only thing they would have to do to make it more violent is to remove the censore. Unless you are talking about guns and whatnot, in which case it's no longer Pokemon, its PokeCoD and stuff.
Anyway, no, just improve what we already have, and make it a bit more mature, like, without little kids calling me to tell me about their rats even after I beat Elite Four and stuff like that. That would be enough for me.
