Here's the premise: we've all had dozens--hundreds!--of moments when games hooked us, surprised us, got us to go all in. (there have been an equal number, or more, moments when we said "you lost me at..." but that's another topic). Pick one and play along.
Dear X-Men Origins: Wolverine,
You had me at the moment near the start of the game when I leaped onto the helicopter in mid-air, tore a hole in the cockpit, pulled out the pilot, and held his head into the rotor blade. Awesome.
Your pal,
Tritone
