I never really got into it as it's nothing innovative and there's no vehicular combat or awesome custom games. That and pretty much everyone on my list still plays Halo so there's no reason for me to play it.
The GGN had a COD tournament for 4vs4 which you/HWM could of got involved in but as we didn't have a team or anyone interested it just goes to show that we're still very committed to Halo
