Props to the OP for moaning about a lack of realism in Halo 3. Considering you're fighting in the 2500's, wearing armour that weighs a ton, using guns that fire lasers and plasma etc., I can't really imagine what realism there is. :/

The CoD4 v Halo 3 debate gets on my tits tbh. Why not just accept people's tastes? Rather than bleating about how so many people are making a mistake playing one game over another. Nothing like forcing your opinion on those who don't want it, eh?
