I play FPS along with RPG and the Halo series is the only one worthy my attention, the story is great one of the best in any FPS (along with the story in HL) the creepines with the Flood, the humorous and savage Covenant, the ring artifact worlds (Halos and theres 7 of them) which are 10.000 kilometers in diameter and are in fact super weapons to kill all sentinent life in the galaxy if all rings get activated at once from a spaceship named the Ark. Each ring has a maximum efficient blast radius of 25.000 light years. The reason to kill all life is to starve the ancient flood to death so they cant feast and infest planets.
The religious covenant belive that if the rings get activated it will bring salvation to all the races united under the Covenant. And theres one human, one super soldier trained by birth who can stop them and thats John or rather named Master Chief, Spartan 117.
The Halo games are really worth to play, it outmatch Half-Life big time and thats not only my opinion. Theres 9 million others with me
Not saying Half-Life is worthless but theres something addictive and special with the Halo games that makes them so unique compared to HF.
If not console games are "worthy" your attention from the PC well then you miss something great. But theres hope, you will be able to play Halo 2 and Halo on Windows Vista, finally.
