Hey, I was wondering if anyone could point me out to any really good tutorials, preferably video tutorials on creating models using Multires? In particular, using it to create a multi resolution model for a game model. 
Maybe here:
You can search this forum for what you are looking for and also do a google search for blender video tutorials models etc.
I think there are a few on Greybeard’s site also. LIsted in the file below.
