@realman543 Man I just spent an entire night figuring out that Microsoft adds an extra argument to the main function in C and wine doesn't support it; I may be the only person in the world who is aware that, under specific circumstances that I don't yet know, WC3 will use that argument.

But I don't recall coming across this one. Here are the exact files the RUNE version uses; given that they seem to be all steam-specific they're probably compatible with other versions of sins2.
