I Gotsa PSP
So I sold about 10 years worth of Gameboy stuff and managed to get a fully paid for (but gently used) Playstation Portable. I bought it, more or less, for one game. Lumines. I played it on my buddy Gilbert's PSP at last year's E3, and was instantly in love. Honestly, if the PSP did nothing but access the internet, play music and videos, and Lumines, I'd say the thing is worth the price of admission.
I also got the Megaman Redux thing, and the Capcom Remix, worth it just for the inclusion of 1941.
Now, I just need more games and more memory.
