I'll throw some other ones out there too
Shadowrun Returns *standard cyberpunk campaign; but its all the player made campaigns that are awesome*
Shadowrun Returns - Dragonfall *fixes issues that were in Returns; my game of the year for 2014; its really that damn good; and again all the player made campaigns*
Ronin - freaking awesome turn based puzzlish kinda game - think spiderman meets ninja with objects and hunting down bad guys. Its hard to explain but so much fun
Guns; Gore; and Cannoli - think metal slug meets 1920s proper gangsters and zombies. This game is awesome - bar none one of the most fun games I've played in awhile. Great one liners - lots of weapons; blowing things up. Killing zombies; the mob etc......seriously awesome fun
Hex - what magic the gathering online should of been.......seirously
Hearthstone - didn't think I'd like it - but its a good time killer; one mistake and you loose the match.
Elder Scrolls Online - turned into excellent mmo - they fixed most of the issues that plagued it from the start; good quest lines.
The Old Republic - just for the storylines alone - and looks to be kinda rebooting in October if you sub; free expansion.
Lichdom - really fun game that makes you feel like you're a powerful mage; really deep crafting - at times I forgot how much fun kiting is.
Skyforge - its in beta; but think of City of Heroes; Final Fantasy 10 skill tree; Aion; with a dash of fantasy and cyberpunk thrown into a blender. You know what so far it works and is a lot of fun. Pretty original concept on way characters are done too.
Wasteland 2 - they just keep on giving with this one; major patch released to fix issue - awesome game.
Pillars of Eternity - Obsidian - extremely good writing - great throw back to BG and BGII - I forget how much time has gone playing; there is a massive world to explore.
I'm at work I'll add more later
