Well, actually, only 2. They are the only 2 games I am really looking forward to being released.
Brute Force
HALO 2
Brute Force has once again been pushed back a few months and won't be released until April 29th now.
It was first announced that it would be released in August 2002, but keeps getting pushed back so they can accomidate all the bugs so it works perfectly with XBox Live.
HALO 2 has actually just gotten pushed back too from August this year, until October at earliest.
Again, a longer wait, but it will be well worth it when these games are impeccable upon release.
If you liked HALO and are looking for a game that will be comparative if not better, these are your best bets IMO, and you can take that to the bank!
