Oh i think this worked cause they recently removed the playability of the full game. Note: this dosent prevent someone from playing the actual game, since they can just make the whole entire game in the editor, but why would you do that work when you can just buy the game? Theres many more reasons to!
1. RESKINS.
2. FBI AINT WATCHIN YOU.
3. YOU SUPPORTING THE GAME DEVS :3
4. JUST BUY THE ORIGINAL.
