Tbh, it's a bit disappointing to me to see a store reject a game that they would accept exclusively because it won't go exclusive. I mean, how much extra trouble would it be to have the game on the store? From a store user's perspective, it's a good thing to have access to good games. I don't really see a good business reason for that decision. I think the fundamental question that customers on any game store have is "will my favourite AAA/indie darling game be here". Answering that with "well it would be if they had accepted exclusive" comes off a bit lame. I know Epic have a tough fight to dethrone Steam (or even become competitive at all) and they gotta do what they gotta do, but I think it would be wise to be a bit politically savvy or they risk getting a stigma that won't wear out soon.
