Wait...? Can i have question?
1. Can we play gmod 9 together?
2. I didn't know that you can make maps for gmod9 ( since i cannot, just for gmod10-11-12-13-14 )
3. I dunno what maps, maybe like a big map... So players can play with a bigger space, i like to make secret in the maps maybe you could too
Maybe try to remake Big city for gmod9 since big city is not there, or maybe try to make a map from your fav games, like i did: Re7, or etc.
Or try to the houses, like idk make farm, or school, or just a house. Maybe the "House with Garden", or other new gmod maps to gmod9
Or city 17, ( it doesn't have to be perfect )
Btw i realized you said what to add to your gm_construct sorry i missunderstood
But it's up to you btw
