Which is your favorite? Halo 1, 2 or 3. Halo Wars doesn't count because its not a first person shooter. Tick off the box in the poll that is your favorite.
It SHOULD be Halo 1 for me gameplay wise, but there's not enough content in it to make it the best of the series. So I'll be going with Halo 3.
Halo 1 for the PC is awesome because of the mods but halo 3 has forge, making them both pretty awesome.
