I own it, i like the new stuff they have added but i was expecting more. Hopefully they will add more with updates. its a source mod that lets you build stuff, script stuff, etc.
i make traps like puttin a large pole on an axis to a floating can in the air, attatching thrusters n a buttno so when u press the button the pole swings down n hits you lol, i also make large structures
i own gmod 9, hopinto get 10 soon. but its gayecause you had to have HL2DM, HL2, and CSS to get gmod 9. i had both until two days before 10 comes out and i finally get HL2. now i gotta pay another $10 to get gmod10. but yea i heard it was buggy.
