After getting burned out on Starcraft, I began a search for some less micro intensive games to try out. I did a couple random searches on freeware.remakes.org and eventually stumbled across a fun little game called Desktop Dungeons.
DD is by far one of the most streamlined and compact roguelikes I’ve ever played. Sessions take between 5 and 15 minutes to complete, and consist of randomly generated single floor dungeons full of power-ups, treasure and dangers. Monsters must be defeated to gain experience, which increases your attributes and allows you to take on bigger challenges and open new parts of the dungeon. Players have a broad range of classes and races to choose from, adding quite a bit of variation to a relatively simple concept.
I am reminded somewhat of Minesweeper when playing Desktop Dungeons, due to how much of the game depends on the random placement of volatile elements. A simple misclick or one wrong decisions can end the game for you, forcing you to restart with a completely fresh arrangement. There is a certain patience required to complete a level (something I have yet to master).
Desktop Dungeons is available for free download on the QCF Design website, along with a few other games that I have yet to sample. Give it a try!
