Yeah, one of the reasons I’m okay with Steam’s DRM is because I know I can remove it and still play them (single player, at least).

On an unrelated sidenote I noticed video games don’t feel fun anymore.

Various reasons for that. It’s probably a mix of you and the games. I notice that I have a hard time staying interested in most modern games and wonder if I’m just starting to not like them any more, but then a game will come along that grabs my attention.
