steam does not compete for exclusivesWhy does it matter if they are Epic developed or not though? It's a competing store that competes with Steam on (among other things) exclusives as well.
Being a new player on a mature field where Valve dominates (to say the least) doesn't come cheap. I'm sure that they expected big loses for the first few years even from the EGS's conception.
so congrats on winning that battle i guess?
