Looks like it's out on DVD and blu-ray on 4/1! Just pre-ordered my copy!
I also enjoyed Unicorn City and All's Faire in Love. Though the latter was pretty much a standard rom-com and the former hinged on a really silly premise (I'm going to get a job with a gaming company by inventing a LARP! You know, that thing that people have been doing for decades! That'll impress them!)
I'd also add to the list the Gamers movies (the third was my least favorite, but a bit of LARPing there, and filmed at a con, for all the good and bad that implies) and for a slightly more serious take, The Wild Hunt (really loved that one).
