1. Mass Effect 1, 2, 3: I have been following Bioware games for a while, but the Mass Effect series was a big surprise to me. The games combine action and role-playing elements in a science-fiction setting that is hard to beat. The Mass Effect games are available for $60 for all three games. They come for Xbox and Playstation.
2. Fable 1, 2, 3: This was a surprising RPG series, that had lots of fun elements. I had plenty of fun playing this, even months after their initial release. These games are available on Xbox and will cost you $10-$18 each.
3. Elder Scrolls IV: Oblivion: This game is awesome but it is somewhat addictive. The good thing is that you can always switch it off since it's not an online game. Oblivion is available on PC, Xbox, and Playstation for $15 to $25.
4. Elder Scrolls V: Skyrim: If you love RPG games, but don't want to spend massive amounts of time online, then Skyrim is for you. The different available quests are very rewarding, and you can play the game again and again as different characters. Skyrim is available for $30 on PC, Xbox, and Playstation.
5. Halo 1, 2, 3: The first time I played Halo on Xbox, I was blown away. I played the game for hours. It's definitely one of the best FPS franchises on Xbox, and the older games are still fun to play. You can get them starting at $10 and more.
6. Halo 4: The latest Halo game was just released a couple of months ago, but you can already get it for almost half price. If you love fast-paced action, multiplayer gaming in a science-fiction setting, then Halo is for you. The game is available for $35 on Xbox.
7. Fall Out 3, New Vegas: This post-apocalyptic RPG is quite interesting, if you like the genre. It will keep you entertained for hours. You can get these games for $20 on Xbox and PC.
8. Star Wars Knights of the Old Republic: If you love Star Wars and Jedi, then this game is definitely a must. You can play a variety of different characters, and complete missions by traveling to different planets. The game is available for $10 and more for PC and Xbox.
9. Jet Set Radio Future: I came across this game for Dreamcast, and when the sequel came out for Xbox I was pretty excited. You'll play as different rollerbladers in Japan, going around trying to escape the police, tagging walls with graffiti to earn points. The game is available for $13 for Xbox.
10. Jade Empire: I picked this game up in a bargain bin and was surprised at how much fun I had playing it. It was definitely well worth the price I paid. You'll create a character, fight enemies and have adventures in Mythical China. Jade Empire is available on Xbox for $18.
