I really enjoyed Paradise Killer, a fun murder mystery game with a really solid soundtrack and neat visuals. I had a great time exploring the island uncovering its secrets and getting to know the remaining characters, and when I finished the game I was done. No loose ends or unanswered questions left, just a nice experience to remember (and a soundtrack to occasionally revisit)

If you haven’t played them the original Fallout 1 and 2 (the Fallout 2 Restoration Project is a big recommend) and Arcanum are classics as well.

Endgame: Singularity is a fun (and sometimes very frustrating) small strategy game worth checking out.

The Dark Mod is basically Thief but really well done with a solid amount of (fan) missions to choose from. Speaking of I should play some of it again.
