That's all I can think of at the top of my head right now.
Halo CE is the best halo to date and best game in my opinion.
You grew emotionally attached to the marines, since they were the only thing to relate to in the whole game. And the way they introduced the flood was probably the best intro for anything in any game I've played to date.
Also I played 343 guilty spark recently when I got my turtle beach's and it is so much more scarier.
1: Halo CE (followed by Reach, H3,H2 ODST)
2: Star wars battle front II
3: Oblivion
4: ME1
5: Half Life 2
