i'll just tell where i really hope for: something like call of duty but then with a squad of let's say 50 men, which you could use as distraction, support or just to run for the enemy leader or something important, online or offline, preferably not just like "kill this person" but something like being the leader of some kinda mercenary squad, where you could take contracts, capture/kill people with bounties, the game called Mercenaries comes close but then with squad and with "standard" huge contracts from different countries, because there you're basically done when killing Song :)
so, if you've got a game that isn't said yet that ahs something to do with this say it and give a bit of a summary...
also i already have all mount&blades, the last 3 call of duty's and mercenaries 1, would love to hear...
