GTA4 meets the '50s, essentially, with Deliberate Values Dissonance and interesting mechanics. If you want a challenge, set the physics to Simulator.

A physics puzzler for people who are 2 parts psychotic, 1 part clever, and 1 part vigilante. Be sure to pause the game when you spot the tooth!

Realism is overrated. Grapple airplanes to street lamps and watch the chaos. Grapple enemies to cars and drag 'em. Weaponize gravity. Or just use guns.

This game will ruin your life, and your fingers, in the best possible way. Confirmed to run on a Compaq NC6000, an okay "Made For Windows XP" laptop.

Because really, who DOESN'T want to jump through a plate-glass window, land on the ceiling, and slip past a guard to hack a computer?

"I AM RUNNING OUT OF FUEL!" times a thousand. Semi-realistic military simulator with boring everything, but good multiplayer.

Much more linear than the earlier games, but with a more interesting...well, everything. Despite all of the new mechanics, it's not newbie-friendly.

Easier than the earlier games, but much more inventive. I'd recommend this to anyone who has never played a Hitman game before, but don't buy ammo!

A game you can share with your whole family (if you don't mind Quake 3-esque blood and gore in unique situations). Loads of fun, though.
