Thought I'd let those of you who use Steam know.
http://store.steampowered.comFeel free to highlight some games you see on sale.
My highlights:
Elite Dangerous67% off (roughly $15 or £10)
http://store.steampowered.com/app/359320/Space simulator that takes place in the Milky Way 1300 years in the future with trading, fighting, piracy, illegal smuggling, and much more in a variety of detailed and immersive ships to fly. Choose the role(s) you'd like to play, buy and outfit your ship to fit those roles, and do it all co-op with friends if you'd like (or strangers, up to you). Very immersive first person spaceship flying. Pretty cool game, it's going to be developed for the next decade piece by piece.
If you decide to buy Elite, you may choose to buy the expansion (which allows you to land on and explore 1:1 scale planets) at
https://www.elitedangerous.com/, as it comes out in December and includes the base game with it.
If you'd like an open world spaceflight and spaceship dogfighting game, play this game.
Chivalry80% off ($5, or $7 for expansion + base game)
http://store.steampowered.com/app/219640/First Person Swordfighting, where you can attack multiple ways, and where accuracy counts. Timing, footwork, and placement of your swings, slashes, downswings, jabs, kicks, parries, and blocks are all important. Very fun online multiplayer game unlike any other. Third person view also available.
The base game Chivalry: Medieval Warfare is with medieval knights and archers fighting, the expansion Chivalry: Deadliest Warrior includes knights and adds vikings, samurai, ninjas, spartans, and pirates. Both are very fun.
If you like cutting off the heads of your enemies in the heat of battle, play this game.
Cities Skylines50% off ($15)
http://store.steampowered.com/app/255710/The city-builder that modern Sim City games should have been. This is an excellent city builder that is smooth to play, fairly easy to learn, and provides a very open platform for you to plan your city however you like. The game has steam workshop mod support, so you can customize however you like.
If you like building, design, and planning, play this game.
FOF (Fistful of Frags)Free
http://store.steampowered.com/app/265630/Fully and completely free first person shooter set in the old west. Uses the Source Engine (Half-Life 2, Counter-Strike Global Offensive, etc). Has a variety of guns, dynamite, and other weapons, and plenty of whiskey to drink. This is a solid multiplayer game with unique mechanics that are fun to master. Despite being free, the devs still update it frequently and consistently. This game doesn't take itself too seriously, which is refreshing.
If you like oldschool gunfighting with people online, drinking whiskey to survive, and not spending a dime, play this game.
