Where Can I Find Portable Game Application? - portable electronic games

Hello,
I am a high school student. During lunch or rest break before the start of the class can be boring, and considering the fact that PED's (Personal Electronic Device) is not allowed or do I walk and talk or go to your computer. Looking for a portable game down. I have Doom 2 on my key but I need more. Games like "Super Smash Bros." or "Team Fortress" or "Halo". something that I think ass friends (one line or network) to play. You can kick you 'help?
