Ok so we have these really poopy Intel dual-core desktops in my school that we use for our computer classes, and I need a few either online or downloadable games to play while we aren't doing anything because we aren't doing anything quite often (it's an easy A class, we don't do much work, and when we do it takes all of 10 minutes), just some addicting platformer or multiplayer games that the computer can obviously handle.
We played Super Smash Land for a while but that got to be repetitive and boring, so any games similar to that would be great. I also tried an N64 emulator but couldn't get it to work because the computer was missing tons of plugins that I can't install because of the restrictions on downloading stuff (but I can still use a flashdrive for other games). Again, multiplayer is preferred, but not as much if the game is really fun and addicting.
