Xbox games

[King Hadas]

Recommend me some Xbox games you guys, I've finally gotten up the intiative to buy an Xbox but now I'm finding since I didn't follow the Xbox's gaming run at all I have absolutly no idea what games came out for it except for some of the major ones.

Here's what I'm planning on getting
Halo (I'll pick up the second one if I find I like the first one)
Ninja Gaiden Black
KOTOR (Same thing as Halo)
Call of Cthulhu (I think this actually came out on PS2 but I can't for the life of me find a copy for that particular system so fuck it)

If you guys could name off some cool Xbox games that would be totally radical.
