Many moons ago, I missed my chance to join a weekly Twilight Imperium play session. Twilight Imperium is an infamously complicated and backstabby boardgame, the kind of baroque strategy space opera that can swallow up entire days and expose any number of terrible character flaws along the way. The Steam version is based on the boardgame's fourth edition, and will feature animated 3D tactical space battles. If you can't wait - and your index fingers and eyeballs are up to the strain - you can play Twilight Imperium in Tabletop Simulator. Back in 2015, Paul Dean interviewed a bunch of tabletop game creators about how they feel about TTS and its copyright-infringing mods.
