By the way If you have ever played Sims u gotta download mods it improves the game 100% the best website is Welcome to ModTheSims2. Also I agree with Tee.h the new garrys mod is pure pwnage
same for garrys mod, it has to be modded - big time.
I find it pretty hard to think what to do..i usually mess around on SP. Like spawning a explosive barrel, welding dynamite to it with an explosive power of 0.1, then using a rope constraint to some ragdoll. Launch it, hit 1, dynamite goes off setting the barrel on fire. And then drops the ragdoll
