I've started to get quite annoyed by that selection menu popping up whenever I want to make a TF2 map, and I want to know if I can safely remove that game configuration without breaking anything important.
I honestly wonder why Hammer++ doesn't come with it pre-removed. Surely they know you're not going to launch the copy you put in the TF2 folder to edit Half-Life maps.
