I've never seen an Indy dev have 90% off, and 80 DLCs... only aaaaa slop does this.
hence my discount comment. high discount = red flag on game is either dead, abandoned, or about to be replaced with the copypaste+1 title of the game.
I'm not knocking sales, just aaaaaaa crap sales since they almost always use 50-90% whereas indy devs seem to be 10-30%.
