HL2 Series compatibility

I think it would be nice if Garry made it so HL2 maps actually work with GMod. Yes, I know there are gamemodes for it, and yes, I know there’s Synergy. But A. Who wants to download that gamemode and then not be able to do sandbox related stuff, and B. Who wants to download an entirely different game?

WHAT ARE U TALKING ABOUT??? IT WORKS FINE!
SURE,U HAVE TO GO THROUGH THE OPENING SCENE BUT WHO CARES???
if i load a map there in Gmod for sandbox editing, i ERASE THE CHARACTERS! THUS, PREVENTING ANYMORE CUTSCENES!!! there, simple!

Try going into the teleporter. Or what would also be cool is if garry could make it so we could disable level transitions. That would be nice. (Yes, I could block the triggers, but that’s a lot of blocking to do.)
