More good news than bad news today.
The good news is it doesn't look like I lost as much as I thought I had. The majority of my networking code still seems to be in place, although I did lose the Text Chat system, which includes my Keyboard Entry parser, so that's gonna' take a bit to rebuild. Further good news is the game compiles and plays again, and runs at 60 FPS again, as intended. I had to rewrite some of my Sprite draw function (the part that keeps it from drawing things you can't see and slowing down the system was part of what I lost, but as far as I can tell, the rest of the Sprite functions are intact). It wasn't a hard fix, though it took a bit to find the problem.
The bad news is that Monogame doesn't support the XNA pipeline completely yet, so if I want to add new fonts or sounds, that's going to take some trickery. Either that or I'm going to have to find an alternative sound engine, but that might be the better option, regardless.
Welcome to 2015 everybody! Let's make it a good one!
