Re: Just works
the last action of the publisher before shutting down their auth servers was to release a patch that removed the drm from the game
Good look getting them motivated to do that, when they've already taken and spent your money.
since the publisher would no longer be selling or supporting the game by that point they could not argue that this represented any lost sales (in fact the counter argument could be that this older "free" version may lead to purchases of a newer version of a game in the series)
And the counter-counter argument being that if a customer is satisfied with the older game, and can continue to play it, then they have less incentive to buy the newly released (yet remarkably similar) sequel to said game.
