Halo 3 takes skill, but that's not to say that nooby players don't get lucky. They do.....alot. Games like Shadowrun and CoD4 do take more skill, just not as much as Halo 3. But then again, those are different types of games. R6:V and CoD4 are more tactical games than Halo 3. Halo 3 does involve tactics, just not nearly as much as Vegas and CoD4. They're different games, meant to be played in different ways. But for what Halo 3 is, it's a great game and people will be playing it for years to come.
