Garry's Mod

The Good
This game have absolutely no limits. If you want build car, space ship or something else, it can be done. You can role play too. And there is thousands of different mods to choose from the tools to the working star gates e.t.c. If building is not going to work you have excellent tools to make comics also, just pose rag doll any pose you want, make it face look funny, spawn some props ant place them, take a picture with camera "weapon", edit picture and voéla, you have made comic. If you have video capture program you can make movies. Or you can just mess around.

The Bad
Well the base of the game is bit simple and have just stuff from the source engine games of VALVe you have installed. If you want more stuff you have go to the Garrysmod.org and download mods and stuff from there. And if you want every or just most of them these downloads take time from playing. And the installing of them is pretty time taking too. You got read read me files to make sure you install stuff correctly without grantee them work.

The Bottom Line
Worth to buy mod, if you are builder, comic artist, movie director or someone who is looking something different.
