What was the First Gamemode you played?

Funny story with my first gamemode:
So I'd seen gameplay of gmod before and i hopped on jailbreak (because id never actually seen it before, mainly TTT and PH) and i got the hang of it pretty quick, and all of a sudden server owner jumps on and being the little kid I was i asked for staff, can't remember the specific but he asked me like a really simple question (Didnt have anything to do with being staff) and BOOM somehow i was a mod (yeah makes no sense right? thats what i was like). This was like 5 years ago and i still talk to the owners of the server. Good times tho
