The original xbox didn't have that many great games IMO. I can only come up with these 3.

1. Halo: CE (The beginning of an era... and for good reason)

2. Halo 2 (Xbox live was the BEST way to have an online shooter back then. Average latency wasn't what it is today. The lower latency of consoles make the experience better than the often laggy PC shooter scene.)

3. Ninja Gaidan  (the graphics of this game impressed me. Big time. Play it upscaled on a 360 and it looked like a PS3 launch title/early port)

4.Battlefront 1/2  (As I recall... I liked being a normal trooper/droid better in BF1, but I loved being jedi, or, most of all, Jango Fett, in BF 2)

5. Crimson Skies (Nostalgia gets this a spot... growing up I loved any and all games that involved flying planes)
