I enjoyed Halo 2, however living up to the expectations of the original Halo it seems to be falling a bit short...
Halo 2 did add a lot the first game lacked such as X-box live capabilities, dual-wielding weapons, and of course more destruction of ordinary objects... However, everything they added to make it a better game it falls quite a ways short in the single-player department and online playabiltity.
Yes, we all know the game stops dead-on in the fray of an excellent storyline but thats is exactly what the problem is, I am not any more anxious for the release of Halo 3.
Online playability; excellent, excellent idea to have it be X-box live capable. However, there are way to many cheaters to make the game enjoyable. I rather play a system-link with my buddies rather than play online. I hope that in Halo 3 they really fix every thing that is wrong with the online play.
