Okay, I'm going to blow $250 on one of these systems in the next weeks.
I know that the PSP started out weak, but now it seems like *the* system for classic compilations (Capcom 1&2, Genesis, Gradius, Metal Slug, etc.), and I'd *love* to play these on the PSP's big, pretty screen. Also, a new Metal Gear action game is out, and a lot of the more mediocre launch titles are going for about $10 used. (Whereas Mario 64 DS is still going for $25 used at stores...) I don't have an MP3 player, and wanted to use a PSP for this purpose as well.
My main problem with the PSP is I'm guessing they'll reduce the price after a few months (in time for its second anniversary), and I'm wondering if Sony is designing a "PSP Lite".
Now, I don't have Gamecube, and there are some games I wanted to play through on that (Metroid Prime 1&2, RE4, etc.). Also I thought Excite Truck was pretty amazing, despite the reviews. (Actually having steering wheel type control without a clunky steering wheel controller is nice) It's small enough that I can fit it in my office desk, and play it on projectors with other graduate students. (I'm particularly excited about Smash Bros. Brawl)
My main objection is that it's $250 for estentially a gamecube with a unique controller, when the Xbox 360 (which I have no desire for) is a mere $50 more. Also, most of the launch titles (sans Zelda) look kind of bland.
In conclusion: I've played both systems cumulatively less than 10 minutes each, so I'm not fit to judge which will give me more happiness. So, for those of you who played both more extensively: which will make me happier?
