I know it’s been forever since you’ve probably even thought about this site/guide any more, but I wanted to thank you for putting in the time to make your guide and continuing to host it. To this day it is still by far the best and most comprehensive info out there on VC3. I wouldn’t have understood half the game’s systems without it!
