I wasn't around when the originals came out, but I have an Xbox console for the first time, and I have to say I enjoyed Halo 2 much more than 1. I had to drag myself through 1 as I found it boring sometimes, but 2 was interesting throughout, it helped that the graphics were redone for X1 I imagine.
Just my 2 cents, I am in no way a Halo superfan. I've completed the first two games from the mcc.
