Half Life 2
Half-Life 2 Garry's Mod V8.3B
Garry's Mod is a sandbox mod for Half-Life 2. There really isn't an aim of the game. People find many ways to have fun with the mod - ranging from making comic books to complicated chain reactions.
Or just putting ragdolls into weird positions. V8.3B fixes a lot of bugs and problems in the earlier version. The loadtimes are a bit faster - but you need to bear in mind that the first time you load a map it takes a long time. This is an issue with all mods - not just this one. I'd like to add a progress bar when it's loading to reassure you that it hasn't crashed - but this doesn't seem possible in the current SDK. If you experience crashing when using the Physics Properties gun you need to completely wipe your gmod folder - chances are that you have installed a menu modification (such as 'UGM') and that's causing the crash.
