So, thank you all for recommendations and info, and for connecting to me on the XBOX
And congratulations to Drakino for Darksiders. I think I am going to buy that.

So far, I have three games:
Forza Motorsport 3
Dead Space
Tekken 6

I see I have none of those recommended by Tony, so I'll try to expand my collection accordingly

But, I am positively impressed by the fact that those that I have are quite fun!
