Cataclysm Dark Days Ahead
Found it about 2 weeks ago. This open source roguelike is the result of a kickstarter after the original developer quit. As a relatively "new" game though already polished it is still being developed heavily.
Modern setting. Zombie Apocalypse. The character can fight using anything from Karate chop (unarmed skill), M4 carbine (rifle skill), cast Chain Lightning (bionics) or stole a military id and access a missile silo to rain down some nuke on the zombie horde. It also has a very comprehensive crafting system. Being able to create your own vehicle is quite wonderful.
All in all the roguelike feels very modern (graphical tiles, source code provided in a nice package making it easy to hack and compile, wiki, modern UI, etc) which goes a long way to make life easy for the players.
Sunless Sea
It received a 10/10 from Eurogamer which caught my attention. An amalgamation of choose-your-own-story, naval exploration and roguelike elements. The setting is very unique (Fallen London setting) and the writing is good. The gameplay is quite suspect however. There are lots of tedium during travel, so much so that I actually just watch a movie when travelling. It still is very unique and probably worth the price of admission for that alone. I'd give it an 8/10. Pretty cheap on Steam.
Just like Cataclysm DDA, Sunless Sea is still being heavily developed. A large patch is coming today.
