It's all about the games, imo. If a console has a game I want, I'll find a way to get the console so I can play the game. Right now, the PS3 has only one game I want...but it's not worth shelling out that kind of expense just to play one game (I bought a Sega Saturn just to play Dark Savior, but that only put me back $35US...that's nothing compared to the $1000US+ investment for a whole PS3 setup). I don't see 2D or 3D as even being a real issue in and of itself when it comes to gaming. But realistically, I couldn't imagine some 3D games being very fun in 2D, and likewise, some games should have stayed in 2D because they suck as 3D.
I'm with WoodyXP on his opinion though; most modern games seem overcomplicated and feel like chores. But what also bothers me is when game developers decide that they want their game to be "ultra-realistic!". Sheesh...I play games to ESCAPE reality, not to waddle around in it some more. I LIKE to be able to jump 40 feet into the air and throw lightning bolts at an army of slimy ugly things. The more fantastic, the better. The onslaught of boring-ass wartime FPS games is the biggest pile of stink in the history of gaming, and most of the games for the Wii and DS are utter crap with their input-method-abusing and their ultra-boring, rehashed themes (HOW MANY f*ckING TIMES CAN YOU PLAY MARIO!!!!!!!!!!!!!!).
Two of the software labels that I code for are considering the GP2X. Daring move, imo, but it should be fun.
