I mean, I can understand wanting all your games in one place which is why I tend to use gog galaxy, but why does it matter if it opens another launcher? Lose a couple of seconds when opening it I guess if that's important, and it's actually steam I often have to open manually as the account joining to gog galaxy keeps breaking but tends to be ok with others.
Just how I feel about it I suppose.
& 2) Epic already abandoned PC once because they thought the grass was greener on the console side, on top of that, called us (pc gamers) pirates on the way out, so hell will freeze over before I buy anything there.
