COD is fun for me when I can play hardcore S&D tactical realism.. Obviously MW2 there is no way to enforce tactical realism so it's shitty - But in prior games, and upcoming Black Ops, dedicated servers allow the admin to setup and enforce tactical realism - which means no spawn tubing / nading (usually an automatically enforced 10-20 second rule on all explosives), no excessive camping (this can be automated as well), etc.. It's a lot funner that way IMO.
