yeah Karasu! that's exactly what i'm talking about XD
and Tenzhi, you're right, those things would be fantastic gameplay additions but the anime and manga came after the videogames' success. the four move limitation is probably kept to prevent overpowered-ness [which is present in the anime idk why], and while i reaaalllyyyy hate that some moves can miss and some moves cant be blocked by super obvious means, and it makes zero sense for a tiny bug to be able to stand against a mountainous goliath monster, those things also lend to the wide spectrum of players the game is accessible to.
also, i'm no game coder/programmer but adding new mechanics like that to battling might be something they dont want to spend time on. CoX didnt really have too many items you can blow up and interact with during battle. and to compare the videogames - limited by hardware, tech and time, to things in the anime which has very few limits beyond a rating is hard to do.
but yeah i want that too
please excuse my rambling, i'm sick and on meds ^_^
edit: i think you're right though, it's probably gonna be a lot of the same thing, just in 3d, maybe one new system [besides new place and critters]
