Fable
The graphics on the demo look fresh and the cinematic soundtrack is impresssive. There are 3 different versions of the same main character, from the opening intro, where you assume the role of a young boy to the darker, still youthful character "killing is the name, mastering weapons is the game." And finally, to the baddest character who sprouts horns and looks like the devil incarnate.

Fable is going to knock you on your but even if you aren't a big fan of RPG games.

Forza Motorsport
Ever heard of a Gran Turismo? Now meet Forza Motorsport. Forza takes all of the best of GT, and adding some Xbox Live, produces one of the best racing games of all time. I think GT will be unseated as one of the all time favorite racing games.

This incredible game allows gamers to drive literlly hundreds of the sweetest rides in the world from more than 60 companys at crazy fast speeds. The level of detail on the tracks is impressive. Every single foot of racetrack was painstakingly re-created to give you the most best looking racing game to date, throw in a huge garage choc full of cars, with millions of different customizable engine/body parts and you have the makings of a classic.

Jade Empire
This game probably won't be suited for everyone but with it's amazing action sequences and RPG type engine, it will keep you playing for weeks and months. coming out of Bio-ware (the comapny who developed Star Wars: Knights of the Old Republic) this action/role-playing game comes complete with an innovative new fighting engine. More than 30 martial-arts fighting styles have been built into it, and only by mastering them and knowing when to use the right ones at the right time will players rise to the top of the Jade Empire.

the graphics are awesome, the stop-fight mode (in case you need to rethink your strategy) is a cool touch, and the overall ambiance was one of a huge, open-ended brawl.
