Is it just me or GMOD never gets old

Gmod is by far one of the funnest sandbox game i have ever played. I dont think there is ever/has ever been a game like it. It is so unqiue in its own was and is always enjoyabe coming back to it. I want to ask if anyone else is that same, like, i just bored of it here and their and I stop playing for a whilem but when i come back to it, it seems as if it just gets funner and funner. Just me?
