Found some great deals during the various Steam-game sales:
Hybrid Wars Deluxe Edition + Season Pass is just €3.50 on
Gamersgate. It's a crazy deal for what you're getting. I've played through the campaign once with one of the characters, and enjoyed it enough to replay it with another one. If you have even the slightest interest in this game, this is a good time and place to get it.
Grey Goo Definite Edition is just €7 on
Steam.Another crazy deal for an excellent game, even if played in single-player only, which is how I've been playing it. The production value is very high and the game feels rather unique in story and concept, despite having familiar mechanics.
Horizon for €7, also on
Steam.
An Indie 4X space game. It reminds me of
Master of Orion in how easy it is to learn and get into, but has a bit more complexity (= micromanagement) built into it. The storyline and epoch (the time period when the game takes place) makes the game feel very different from other 4X space games I've played, it feels closer to our current scientiic and technological limits than other such games.
Styx: Master of Shadows is just €7.50 on
Steam.
If you are tired of regular stealth games and want something very unique and different this might be for you. You play the goblin character from the game Of Orcs and Men, with the game taking place within the same Dark Fantasy game world.
Mad Max is just €5 on
Bundle Stars. It's one of the best AAA games I've played. If you like open-world vehicular combat and simple but cool action, it's a true bargain at this price.
Men of War: Assault Squad 2 - Complete Edition is about €7 on
GMG. It's the lowest I've ever seen the Complete Edition at. One of my favourite strategy game franchises, and quite possibly my favourite game
within the franchise.
