In part because I don't have the time to devote to becomming particularly good, I don't really focus on playing videogames online anymore ... When I evaluate Halo games I am talking (primarily) about the single player campaigns.
With that said, the Halo games' single player campaigns have always been very average and their main selling feature has been their multiplayer gameplay ... Being the introduction for a lot of console gamers to lan gameplay Halo became legendary, and Halo 2 followed that up with being an adequate introduction to online gameplay for these gamers; there is nothing particularly special about Halo 3.
What makes a lot of gamers dislike or hate Halo is that it is such an overhyped game series, and there are many more worthwhile games which don't get the attention they deserve because of games like Halo.
