While the current plan for Limited Run Games is to slow down a bit in the coming year there's still a backlog to burn off, so another week sees another pair of releases.  This Friday is a solid double-shot of action gaming with Sky Force Anniversary and Croixleur Sigma, both of which come in PS4 and Vita versions.  Sky Force Anniversary is the console version of the first game in what's now a series, upgraded from its mobile-gaming roots to full console (and PC) glory.  Croixleur Sigma, on the other hand, is a Japanese arena combat game, a little on the short side but built around replayability.  Sky Force Anniversary has 3,000 copies on PS4 and 2,300 on Vita, while Croixleur Sigma clocks in at 3,000 apiece on both PS4 and Vita.  Those aren't huge numbers for these two, both of which have a built-in fan base, so while some of Limited Run Games' releases have been selling out at the more relaxed pace of a couple of days recently it's probably a good idea to get there early for this batch.
