Warning: This title uses 3rd party DRM (Ubisoft Uplay)

Means you need to play it in Uplay usually, basically when you launch the game you have to log into a uplay account, its not a huge deal but a slight annoyance.

Yes, at the system requirements you can see you need an uPlay account and an internet connection for activation :)

When you try to launch the Ubisoft game through steam Uplay will open which is Ubisoft's game launcher. It does require an account and an internet connection to install Uplay and any client updates. If your game is bought through steam all game updates will be done through their. Also if you have friends you want to play Co-op or multiplayer with you have to add them and join them through Uplay.

So you have to log in with Uplay and need an internet connection every time you start the game?

Well if that's the case I hope it dies like Games for Windows Live did...

Thanks for the info guys~

Just like you need steam to play the game ubisoft games need uplay which means when buying through steam you end up needing both steam and uplay open to play.

I know you're talking about Child of Light :p
