I was browsing games just now and noticed that Deus Ex (As well as a few other games like Thief, Syndicate, etc.) have EULAs on their game overview pages. The EULAs say that the games may require Origin, might collect data to send to the publishers, may download ads to display in-game, etc. What's up with that? Are they just generic EULAs that GOG had to display for some reason or do the GOG versions of these particular titles actually data mine or feature in-game advertising?

I just found it odd that only a tiny handful of games on GOG have such an EULA attached.

I have no idea what that's about, and I think you'd be better off asking in General DIscussion; the GOG.com staff are much more frequently seen there.

I will say that it makes no sense for any GOG.com games to require Origin (or any other client) because that then means they are not DRM-free.

Also, in Deus Ex's EULA, both times "origin" appears, it's part \of the word "original."

As far as in-game advertising, that is exactly the same between Thief and Deus Ex, so it's probably generic to Square Enix's games here, and intended for their newer games.

Oops, I meant Syndicate. Syndicate's EULA mentions Origin.

Anyway, I just find these EULAs odd. It seems that only EA and SE games have them, and the contents are mostly the same between games. They all mention the game using in-game advertising that updates when connected to the Internet, they all mention the games collecting user data to send to the publisher, the EA ones all mention that installation of Origin "may" be a requirement, etc. I know that GOG would never sell games with DRM because that's against their business practices, but what's up with the EULAs attached to EA and SE games?

As far as I can tell, EA pretty much just slaps a generic EULA onto everything regardless of how relevant any given clause is.
