KrAzY:

halo 1 had a better plot.... i liked the sence of smallness and discovery from the first one.....

 

but halo 2 has better gameplay...

 

i prefer 1 tho (assault rifle!!!!!) 

I agree. The feeling of total desolation and chaos, especially in the first couple levels, was really neat. It made co-op even better because you had to rely on your teammate to watch your back because nothing was certain. Throw in a couple frightened marines and you have a great psychological game. I hope they can replicate that feeling in Halo 3. Somehow they lose that in Halo 2's singleplayer.

 
I am looking forward to Halo 3's massive ground battles though. It won't be "desolation" but it should bring the real chaos back.
