Star Wars: Battlefront 2 is a favorite of mine for many reasons. Among them is the sheer destructive chaos you can create.
I was playing on one of the maps (The wookie planet I think) as Yoda. I was kicking ass left and right when a group of tanks and heavily armed droids came by. Within about 10 seconds, I had destroyed the droids, the tanks, won the battle (after a minute, only 1 droid left) and left a trail of dismembered robots in my wake.
