So there are 2 games I've been playing pretty consistently recently:
Caves of Qud - It's a roguelike RPG with very simple graphics, but deep gameplay. Currently in Early Access but constantly seeing improvements, it's worth buying on sale if you like post-apocalyptic RPGs. It has a fun feel and a lot of replayability. But if you need more of a pitch, here's this:
The other game I've been playing is probably of more interest to the group here: Warhammer 40k: Sanctus Reach. It's a pretty good implementation of the tabletop rules into a PC format. While it only has 2 armies currently (Space Wolves and Orks), they are well-done. I haven't played 40k since 3rd edition, so I honestly don't know if it faithfully reproduces the tabletop game, but I know it really feels like a tabletop game. And while I'm no huge fan of Space Vikings, I do love Space Marines in general and love the feeling when my Terminators shrug off round after round of gretchin blunderbuss shot.
It also lets you design and field your own army from a list of possibilities, which I always loved about the tabletop game.
