I feel like I should have an opinion about the just-announced PSP2 but hate commenting about handhelds because I'm not their target audience. The truth is I spend most of my time where I want to be and little time in transition where a handheld is important, so the vast amount of time I spend gaming (in itself an impressive amount of time) is in the comfort of my own home, where nearly any handheld experience that wins my attention must do so versus a stack of "living room" games, and almost always has me wishing at some point that it was made as one, where I didn't have to squint my eyes and crane my neck to enjoy it. The PSP2 lineup, with its Uncharted's and Resistances, seem to fall into this category.
If I think of game experiences I actually prefer on a handheld, they are things I wouldn't want or can't have on my TV, (a) like brief games (Angry Birds), (b) "low-res" games (Scribblenauts, Phoenix Wright), or (c) games that take advantage of their unique input due to their small size (the first Zelda game for the DS).
Oddly, the games I've noticed for 3DS also fit few of these categories, making me shrug at that system, too. The most interesting things have been the app that makes virtual reality out of what it sees via the camera and lets you shoot at it (a,c), and the 3D camera.
I know I will be tempted by the new handhelds, but both -- especially the PSP2 -- look to deliver experiences I once again compare unfavorably against my living room games. This is the kind of thing, however, that I prefer to be wrong about. Since my data collection is incomplete, I still hold out hope of spotting news that lets me feel like I'm part of the handheld club.
