If I want to play a more technical 1-on-1 competitive game, I'm probably not going to be playing a Power Stone game at all.
I don't want to play whatever other game, I want to play Power Stone. It's not about being super technical (though you can get really, REALLY good at it), it's just a lot of fun and there's nothing else out there quite like it. You can pick up objects like chairs or tables or you can vault them and toss them behind you, or you can just push them towards the other player. You can jump off walls, grab on to poles, and cling to the ceiling. You can homing attack off walls and poles, diagonal jump kick, air grab, ground pound, etc. At any given time you have a wealth of options available to you, all dependent on the stage and what is nearby, and they're all cool. That whole game is almost totally gone from the sequel.
Power Stone 2 was simplified way too much, added really jarring characters that don't mesh well into the game at all, and has the environment hurt and kill you probably more often than other players. It's like every level is fucking poké floats.
I wanted a refinement and an evolution of what made the first game special and we didn't get that at all. We got a completely different game type that has very, very little to do with the first game that I loved. That made me sad. I'm sure there are some positive aspects to the game. They should've just made some Capcom All-Stars Melee/Brawl type game and made a real sequel to Power Stone.
