I just won an xbox from work, it's the elite version. And I'm not too good with video games, like I have the wii and I like mario and what not, what kind of easy games come on xbox

You can buy Microsoft points and download arcade games

It really depends on what kind of games you are in to playing. Most of the roll playing games have the ability to set the play level to easy. I would suggest buying used at GameStop or renting from Gamefly (like netflix but for video games) so you can see what games fit you best.

Simply go on YouTube and look at gameplay and reviews and just pick the games you think you might like, or just rent games from the video store
