I can imagine a World War I game working well for large, open multiplayer games. For multiplayer, you could have all sorts of different maps set all over the world, and an interesting variety of weapons too - there were some pretty interesting experimental weapons made during WWI which could easily be incorporated into multiplayer. Heck, it'd be a change from the ultra-tight CQC maps seen in CoD these days. Maybe they could even bring tanks back from the CoD3 and World at War days.

But it'll probably never happen.
