At this point, my biggest concern about Barkley 2 isn’t whether it’ll ever actually be released, but that if and when it is, it’ll no longer have anything to say.
Shut Up and Jam: Gaiden was a fantastic parody of the then-contemporary glut of janky RPG Maker fangames (while at the same time being a completely straight example of the very genre it was sending up!), but a decade later, indie CRPGs are doing in earnest what Shut Up and Jam: Gaiden did in jest, and doing it well.
From what I’ve seen in previews and such, Barkley 2 is doubling down on the critiquing-the-state-of-the-indie-game-dev-scene elements of its predecessor, but it own development has been been grinding along for so long that I’m half convinced what we’ll end up with is a game that has a lot to say about 2012′s indie dev scene coming out in 2020.
