Arma: Cold War Assault, Bohemia Interactive's debut game published by Codemasters as Operation Flashpoint in 2001, became genre-defining combat military simulation and the No. 1 bestselling PC game around the world and has won many international awards, including “Game of The Year” and “Best Action Game.” Over 2 million copies of Operation Flashpoint have been sold since its release.

Storyline

JASF is an arcade combat flight "sim" - think HAWX on a lean budget, with no cockpit view and a 30-fps framerate cap. Each completed campaign mission unlocks a couple new plane models or variants. Matchmaking multiplayer will also let you play the campaign in 4-player coop, or setup various competitive game modes.

SpellForce: The Order of Dawn is a combination real-time strategy and role-playing video game game developed by German game developers Phenomic. SpellForce focuses on the RPG elements of controlling an avatar, and on many levels the RTS elements of leading an army as well. The player begins by creating a hero, called an avatar, and then selecting which character properties they want their avatar to begin with. Besides the storyline, there are also plenty of side-quests, that when successfully completed, usually grant experience and/or item rewards

In a victorian world populated by nesting dolls, you are Charlie the underdog, on a quest to find and rescue his scattered family. As the smallest doll around, Charlie can "possess" unaware bigger dolls and use their special abilities to solve puzzles.

Microsoft Flight is a free to play flight simulator very reminiscent to the older Microsoft Flight Simulator products. This one is based around Hawaii and lets you just fly about, do some geo catching, or fly online with others via multiplayer (GFWL).

While the title is indeed free to play, the catch 22 is that if you want additional planes or areas its DLC that you must purchase.
