Aside from the fact that I hold a heavy bias against the PSP, I see the whole UMD format as a severe waste of money, and 3D graphics don't have the same impact on a portable screen. DS is a better choice for me because I prefer classic gaming over most modern forms.

And there haven't been too many games for the PSP that grossed very well. It's not a gamer's system. It's multimedia. But I still don't think it's worth it.

When I buy a game system, I do it to play games. That's why I choose DS.
