Gary's Mod

I've played this game before and this 2011 game is becoming more popular nowadays. It's fun because it's a sandbox game. You can kill your least favorite character or your have your favorite character follow you and use a gun (or stun stick, which still kills them). Go and Hide and Seek or create a Zombie apocalypse. The main problem with this game is the loading screens because when you launch the game it will take 20 minutes (for me) to load all the programs, mods, and severs. With an additional 10 minutes to get in the server. That's the only the main problem for me at least.
