hmm... since halo wars hasn't been released I don't think I could base my opinion on that. although I have seen the previews. And I'm not a real halo fan either. But I like GTA4 a lot more than the GTA series because it's free roam and you don't have to follow one singe story line. you can make it up as you go. I like the free roam games a lot.
so GTA
