When Halo was released on the xbox back in 2001, there's was no competition on any platform in terms of graphics, A.I. and gameplay. It may not have been as deep as System Shock 2 or Deus Ex, but the combat was unmatched.
After all this talk about Halo 2 being leaked a month before its release, i wonder how the responses would be at this forum when KotOR II (full xbox-version) probably leaks out onto the internet within the next 8 weeks?
