if you have a 360, there was a compilation of all the q entertainment games (lumines, every extend extra) and for some reason rez hd called "qubed" which you can probably get for pretty cheap.

I'll try to add mine later. Awesome console.

I have E4 on the 360 was never really a huge fan of it compared to just EEE on the psp, great bosses in the psp game.

yeah, it's just a better handheld game. so is lumines for that matter.

in other news, they need to put eee on psn. i want it on my vita.

I got a PSP just to watch movies at work. The game I got with it (Rainbow Six Vegas) is STILL in its original packaging! I soon learned to love it for its games and other features (still have over $300 in comics on a memory stick). My top 10?

1: Hot Shots Tennis Get a Grip--handheld crack cocaine.
2. Tetris --The greatest puzzle game of all time
3. Syphon Filter Dark Mirrior --Big screen prodution values on a small screen
4. Resistance: Retribution --A great graphical showcase for the portable
5. Final Fantasy Tactics --best game on the console....if I hadn't played it annually since like 1998
6. Metal Gear Solid: PeaceWalker --ambitious beyond words
7. Burnout Dominator--great stress reliever
8. Valkyria Chronicles II --If only the battlefields could support more soldiers
9. Crimson Gem Saga --my favorite JRPG on the console
10. Loco Roco--charming little puzzler

Darn cell phone. Posted before I was ready!

Anyway, shout outs to:

Little Big Planet, Pursuit Force, Patapon, God of War: GoS, Jeanne D'Arc, Jak and Daxter, Silent Hill Shattered Memories, and a few more that I can't remember because my Vita battery is dead.

Also, Crisis Core since it's the sole reason I still have my PSP out.  Needs a digital release!!
