What's your favorite Gmod gamemodes?

This is what the title is saying, mine are Zombie Survival, Prop Hunt and Trouble Terrorist in Town,

Pirate Ship Wars and Morbus

Sandbox, DRP and Gmod Tower when it was a thing.

Naval Play 2 for sure, flood and sled build are also some good mindless building fun.

I guess Dark RP too if you count hobo trolling, the ability to build in public is very strong in the right hands.
