GOG also has no DRM'd games, at all. It's truly amazing, and if possible, I always buy from them.

Not exactly. Quite a few EA games on Steam will give you a license key that can be activated on Origin. In some instances they might use a generic key that might not activate, but you can ask Origin Support to activate it on Origin for you.

The hate for Origin was mostly hate for EA's greedy practices and some privacy related stuff that came out when their client was released.

Origin does it as well but only with EA games. Ubisoft does it for their abomination as well.

origin has something similar. Letting you activate old games on their.

Well, GOG also gives you an executable which is rare these days.

You can click and drag it onto your friends' computers for a quick LAN party or to let your girlfriend play alongside you on a airplane.

I never hated Steam more than the time I was on a 18 hour bus ride only to find out Steam wouldn't even launch if it decided it needed to check for updates and you had no internet connection. And there was no way then to play the games you paid for.

If a game you want is available on both GOG and Steam, it's almost irresponsible to get the Steam version.

Oh yeah, on that same bus ride, I found out that .azw-formatted ebooks are locked to a single Kindle. I'm ready for GOG Books.
