Personally, I prefer a good round Command & Conquer: Zero Hour. I like to ring the bases of the Kerry supporters (and those of their terrorist allies) with snipers, and then send in the hypersonic Aurora bombers to deliver a few tons of fuel-air bomb goodness.
Afterwards, I send in the AC-130 Spectre gunships, along with several Combat Chinooks full of special-ops troops to mop up.
And I don't take prisoners.
Even if you don't like FPS games, get it just to stroll along the beaches and climb the mountains. And fly the hang glider.
