I held off on buying an Xbox on launch day because there really wasn't anything on it that I *had* to play. Halo is a great game but it would never have held me over.
When I went to E3 in May, I was really impressed with Splinter Cell, which trust me on this is just about the coolest game ever made and I'm DYING waiting for it to come out. Then there's Toe Jam & Earl 3 and Panzer Dragoon Orta, two gorgeous Sega titles. When I got back from the trip, I went and bought one.
Naturally I picked up Halo, and I've spent some time with Morrowind and Dead to Rights but so far this system is still getting way less playtime than GameCube and PS2 around here. Hopefully the new games will change all of that, I'm counting on them!
So what are your experiences with Xbox so far, if any?
