Not surprisingly, some backers are upset. The timed exclusive has been likened to a "bait and switch" or even false advertising -- players expected a Steam release and now won't get it until months later at best. Some have said they'll seek refunds, while others are more concerned about the implications of releasing the game through a store that currently lacks features Steam users take for granted. Linux support is in doubt when that's not even an option through Epic's portal, for example.

Not everyone is opposed to the move. Some note that this might have been necessary to get the game across the finish line, while others noted that Epic's more developer-friendly royalty cut could be appealing to a small outfit. However, there's no question that this is a big gamble. Mobius is wagering that the exclusive won't alienate too many backers on the road to launch, and that its larger share of each sale will be worth going to a younger, smaller store that doesn't always have a great reputation among gamers.
