A great tycoon game with a huge amounts of missions to play. Includes the expansion, which adds more goods, vehicles, and missions.

Because killing all humans is fun! The wide variety of different disease types gives this big replay value, especially trying to get achievements!

This game is not for the faint of heart, but it is an exquisite Grand Strategy game of politics and industry set in the 19th and early 20th century.

A lot of people still consider this to be the DEFINITIVE version of Civilization, possibly even better than Civ 5. Make sure you get Beyond the Sword!

Arguably what Diablo 3 should have been...and it's free! A really incredibly good action-RPG with a great free-form skill system.

A *fantastic* strategy/puzzle game that no one knows about. Use your collection of ghosts and ghouls to scare people out of homes. Incredible fun!

This city-builder gives you a HUGE area to work with. Performance isn't great in the late-game, but you can really be creative in Cities XL.

While not for everyone, this is a really good simulation of what it's like to drive trains! Lots of DLC for new countries and such.

Simply the best railroad/business simulation game on the market. Can't recommend this enough! NOTE! Needs special tweaks to run on Windows 7/8.
