This is my only gripe with LRG games and why I'm reticent to order from them IF (and only IF) the game is going to get published and sold via retail stores anyways. With SOR4, I wanted to support them, but I'd rather get it EARLIER so I can play it (I only buy physical games).
For other smaller-run/lesser known games, I'm super grateful LRG brings those games to physical release. Will always try to support those releases.
That all said, it's unfair for LRG because games like SOR4 and Shantae probably became popular enough to get larger physical print runs BECAUSE of LRG, and its developer-friendly approach towards not demanding exclusivity. This, however, does mean LRG will sometimes get burned. Kudos to LRG, though, for honoring cancellations on SOR4. They're a solid company, and I hope they're around for a long time.
Shantae was pretty popular before lrg, I wouldn't attribute them to it's popularity in the slightest
