Hi there.
Let me say first that i don't own GR2 yet but i would insta-buy it when needed ...
So let's go to the point. I've opened a thread in GR1 Modding which is kind a Theorycrafting Post about Lua, Sockets, logics and whatnot. Please, if you're interested in a MP mod, visit that Post and let some (helpful) feedback there.
I also need a second Person to test code then because i don't want to fiddle around with sandboxie again. It gave me headaches ^^
