Yeah, I bought the PSP mainly for the "extra" features such as music playback and the Internet browser. I have a few good games like the Sega Genesis Collection, GTA: Vice City Stories. But I've noticed the PSP doesn't have much variety in games as the DS. PSP games are pretty much dumbed-down PS2 ports, and that is partially why I wanted to buy one, since a PSP is basically like a portable PS2. But on the other hand, the DS has more original games like New Super Mario Bros, Nintendogs, Trauma Center, Brain Age, Advance Wars, Castlevania, Mario Kart DS, Pokemon, etc.
I guess I'll go back to GameStop and trade in my PSP with the 4 games I bought and get a DS instead.
How much would I get for it? The PSP was $145 (used), and I bought 3 used games (Metal Gear Solid: Portable Ops +, Sega Genesis Collection, GTA: Vice City Stories) and 1 new game (Sonic Rivals 2). How much would I get for all that?
