First thing I'm going to say about the Xbox 360 is that the graphics are awesome! We own two consoles as we were always arguing as to who would play first.
The best game has got to be Gears Of War, both online and single player its just an amazing game and Gears Of War 2 is coming out soon, can't wait!
Another one of my favorite's is Crackdown as it has loads of little missions to complete apart from the main game, online and offline its a brilliant game.
Bioshock is good but it's downside is that it's just one player like Condemned, I like having the option of playing live.
The Burnout series is very good as well it's one of my favorite racing games as its not just racing you have to do. I prefer Burnout Paradise as the online game play is better than Burnout Revenge. Army of Two is also very good.
I've had a good laugh playing that online.
The best thing about the Xbox 360 has got to be the achievements as you can compete with your friends to see who gets the higher gamescore.
If you have two consoles can you link them together to play each other?
Yes you can all you need is:
A Xbox System Link cable or a Crossover cableOR a router/switch/hub to connect each console together with RJ-45 Ethernet cable
You can also system link an Xbox and an Xbox 360 together as long as the game you are playing is backwards compatible
How could i forget GRAW2 is also one of my most played games both single player and live, spent quite a few nights playing it live and met some good friends aswell.
