Knights of the Old Republic: You'd be surprised at how many enemies normally classed as "immune" to Force Wave are really "no, the DC is way too high for you to... wait, what?!" Stack your wisdom high enough above 20, and this includes Darth Malak in the 1st and 3rd stage. Combined with an obscene number of landmines... let's just say that building a Consular/Scoundrel Jedi who specializes in demolitions and armor wearing isn't as insane as it sounds.
Rainbow Six 3: Raven Shield: When playing in the penthouse level, take a heavy machine gun up to the room overlooking the staircase and main area and set it up through the blinds. You'd not believe how much confusion that inspired as to where the hell I was.
Mass Effect: Weaken defenses of an enemy with Warp, follow up with Singularity, get under target and fire Throw. You'll be lucky to ever see the body come back down, especially on Feros.
Chaos UT (Unreal Tournament 2004 mod): Set up a dozen or so Proxy Mines (evil bouncing smiley faces) around a corner, and when they inspire panic, follow up with bouncing blades from a C.U.T.T.E.R.
