O.K., so... I have heard of this new version of Garry's Mod 13 while playing Garry's Mod 10, and im not to happy with what I have seen so far.

There takeing Sandbox mode out of Garry's Mod!!!!! Sandbox is the reason I bought the game! Im definatly Not recommending Garry's Mod 13 to ANYONE!! Im very dissapointed with this news. Anyone who might agree with my statement, please leave a comment. Thanks ( but not to Garry's Mod ! )
