H3 was great by bungie standards, but really have you played reach and odst....terrrrrible. but H2 was decent, ever since bungie gas been on the decline. H2 was skill, H3 a little less, reach a total noobfest. and odst doesnt even count as a game, it would barely make a good add-on
Personally I think Halo 2 is the best game but i have never played the multiplayer. Then Halo 3, then Halo 3 ODST because i really like the campaign and firefight, and i like Reach campaign and firefight, i also like multiplayer but i agree there are too many noobs
