Well, all Steam games have Steam DRM? The Steam store will tell you if there is additional DRM on top of Steam, at least it has in the past.

To the parents question, it is better to use GOG if you care about DRM.

Sometimes the Steam version is qualitatively better because the publisher/dev has supported the Steam version with more updates. Often the updates do turn up on GOG, but it's possible there is a delay.
