Gearbox comes across bad after this whole mess, but ultimately, its Sega's responsibility to put out a quality game, if they expect it to sell. Sega should've stripped them of the title, and passed it on to another developer.
As it stands, one of Sega's "pillars" has completely crumbled. And I don't think they can release enough Sega Vintage collections to compensate for how much Aliens cost them. Though I'd appreciate a Shining Force III port to XBLA.
