No, I wouldn't suggest vechiles be added, since that's never been what Call of Duty has been about. As Dixon has said, perhaps some new game mode, perhaps modes where there are more than two factions, I don't know, something that expands upon the excellent system they came up with for CoD4. I think Killzone 2's in-game switching of objectives is a great idea, but perhaps one that could be expanded upon to be a more dynamic.

At the very least I hope IW work towards ironing out some of the issues that eventually ruined CoD4 online for me, the reload and geometry glitching, that kind of thing. As excellent as CoD4's multiplayer is it's not perfect, and I would be somewhat disappointed (and surprised by IW) if they just churned out the same online mode again.

Of all the games to namecheck when trying to provide an example of why the other style of accomplishment is not as satisfying, Call of Duty 4 strikes me as a very poor choice. Why purposefully compare your title to one of the most successful games of recent years, especially when trying to say that they could have done things better?

As others have already stated, a little challenge and difficultly is no bad thing, and a few more games could suffer to add a bit more. That said, one thing that has been bothering me recently is that a lot of games seem to still be relying on cheap tricks and tactics to ramp up the difficultly.

I imagine I'm far from alone in how excited I am for Modern Warfare 2. One thing I really hope they do is push the multiplayer aspect of things further, rather than relying on churning out the CoD4 online game again (as Treyarch seemed more than happy to do).

Sorry, but UE3 isn't the only middleware engine out there. To make such a claim is more than a little naive.

I'm not suggesting it is all roses, far from it; what I am saying, however, is that the poor workman shouldn't blame the tools.
