Smod and Garrysmod, definitely.
And if you don't have the money to buy Gmod (Who can't anyway) you can just download Gmod 9, and older version that's still available on Steam, but you'll need Counter Strike, Half life 2, Half Life 2 Deathmatch.
..Wait, i actually have those, i think i'm going to go time travelling to the past Gmod.
