PSP: I'm submitting

[Dyne]

So, I calculated how much I make next week, and.. ooh, wow. <3

So anyways, I have two options: filling out my gamecube library completely, or buying a PSP. The thing is, I really like the PSP, and it looks hot as hell. But I could care less for the games on it.

Persuade/Dissuade me. I'm leaning towards Metal Gear Ac!d or Lumines, but I don't know. I usually like non-turn-based Japanese games, and I'm a bit iffy about replay value here.

What about Hot Shots Golf? I'm a huge fanboy of Mario Golf. Is it any different?

What are some of the things I can do with a PSP?
