My favorite personally, was halo 2 because thats when they were first introducing dual weps and more variety of weapons and splitscreen maps.I think halo 1 is more user-freindly..
Halo Reach seemed just like Halo 3 (yes I know that it is different). Halo Reach would be a great game by itself but there weren't enough improvements from Halo 3.
I have great memories with Halo 2, for it is the game that got me hooked on Halo. I was talking to some friends about video games, and they brought up Halo. I told them I had Halo 2 but had never played it. So some friends started coming to my house at random times and asking to play, so I just ended up telling all my friends to come on Fridays for conveinence. Thus, the weekly Halo tradition was born. After about the third week, I explored what the heck a "Ghost" was, and found the lovely mechanic of boosting into my friend's faces and SPLATTERING them. To me, a splatter is just so appealing. It just sounds good. You have snipe, assassinate, pummel, stick, supercombine explosion, and many others, but my favorites are Splatter and Beat Down. This lead to my Gamertag, Splada Splada.
I once played Halo:2 when i was 8 or something and i liked, unfortunately i forget the name until my brother bought Halo 3 and i remembered it. Now i have Halo:Reach and i keep on playing it it never gets old. I really look forward to the next Halo, it's a shame Bungie stopped.
I loved halo ever since playing the second one all those years ago. I still haven't played #3 but I enjoy looking up stuff on you tube. I hope they make a halo movie.
