There isn't much to dislike about Epic store
Unless something has changed and I've missed it, Epic is the only PC Games storefront Buying Exclusivity rights to their store.
That's probably my biggest gripe with their service and why I refuse to use their service more than anything. The free games is a marketing ploy because it's pretty much the only way most people would even consider installing EGS over/next to Steam, IMO.
Leave exclusivity to the consoles, where it's necessary for competition in hardware sales. Trying to make PC games exclusive to a specific store software is petty and desperate.
