So I never got around to playing the first two Batman games... I prefer to play on my PS4, but they never got released for that. They are each on sale for only $4.99 for Mac via Steam as well as the Mac App Store... Which to choose? I'm leaning toward Steam, in case I ever get a Steambox or something like that. Is there any reason I'd want to get them on the Mac App Store instead? THANKS!
