You should create a tool for this game that checks for updates

I don't owe anything. I just do what I want.

That's okay, no problem with that

You should recreate the Combine Advisor from Half-Life 2!

What happened to Quake Sandbox? Is MiLab still alive?

Sourcetech is new Mitech

Opensandbox team is new milab

Opensandbox is new quake sandbox

Hmm, you need place /game folder with your executable.. i doesn't have mac..

Yo i'm not gonna lie the graphics are fire! Create higher graphics whenever you create a new engine
