Chances are you've already heard of this incredible game. If you haven't, this is an Action RTS hybrid with asymmetrical gameplay in which you play as one of four very distinct races, the last of which is an all consuming giant.
Grim Fandango: Remastered. Need I say more? If yes don't take my word for it, go watch a youtube video explaining why you may or may not love this game. It's an absolute classic at what it does.
Icewind Dale is a linear role playing dungeon crawler with occasional RPG elements in which you take a party of custom created heroes across the Spine of the World. If that sounds like your style, give it a try. Personally I missed the RPG in BG.
Don't buy this on Steam, buy it here, the Steam Version is bugged and unplayable on a lot of systems. Jade Empire is a Kung Fu Action Role Playing Game with a great cast of characters and a lot of moral decisions that influence the story and ending.
Play as a cunning Machiavellian space hydra who's role is to preserve civilization by assuring the formation of a peaceful federation, or the extinction of all the races you don't get along with. It's up to you, play it your way.
There is a Game of Thrones mod for this game. Any mount and blade game is worth having, this one is worth having mainly because it has the most amazing mods. In it, you play as a mercenary who recruits and trains an army, the rest is up to you.
The controls and camera suck for the base game even if the story involves some interesting decisions. However the expansions developed by Obsidian handle excellently, and Mask of the Betrayer is a truly interesting campaign you can skip straight to.
A fun unique Action/Puzzle/Adventure game in which you control an evil overlord capable of controlling an army of imps and sending them forth to terrorize towns and solve puzzles.
A charming 2d God Game in which you control giants with magic powers over nature that move along the equator creating habitable land for greedy humans to settle on. Be careful not to give them too much too fast, or they may attack you when you can't.
One of the great classics despite a few technical hiccups and dated graphics, the world, characters, plot, and paths you may take are engrossing
