Aurora

Aurora is a semi-turn based strategy game reminiscent of a blend of traditional 4X gameplay (such as Master of Orion) and military naval simulators (such as Harpoon or Jane's Fleet Command). It's sometimes referred to as "Dwarf Fortress in space", as it possesses the same depth and storytelling capability as Dwarf Fortress, as well as the incomprehensible UI and frustrating bugs. The game follows the management and military deployments of one or more player races as they colonize the galaxy and encounter other lifeforms. Aurora was specifically designed with storytelling features designed to easily support Let's Plays, making it one of the first games specifically containing features for Let's Players. For instance, characters in Aurora possess personality traits that have little or no effect in game, but can be easily parlayed into developing a personality for that character when writing a narrative LP.

An epic, multi-year, crowd participation LP of Aurora entitled The Coldest War is ongoing on the Something Awful forums, beginning in March 2012 and as of October 2014 is still active (most likely slightly past the "midpoint" of the LP's plot). The Coldest War has proven extremely popular with over 15,000 posts and over 716,000 views as of October 2014.

Due to Aurora's nature (turn-based with variable-length turns of between a few seconds and several months), it is only really suitable for SSLPs.
