It's all opinion. Personally I prefer the look of
1. Gears 2 - Biggest game of the year. Best graphics to date.
2. Fable 2 - Lived up to the hype and best RPG of 2008.
3. Left 4 Dead - amazing developers and they have never dissapointed.
4. Banjo Kazooie - Previews of late have all been great.
5. The last Remnant - Should get JRPG of the year.
