Wow, I chose the absolute WORST day ever to post an update. So ummm.... now that some mods are P2P now and will only be updated if you buy the Steam Workshop version, the Skyrim guide will probably have to be reworked a little bit. In any case I do not plan to buy any mods and no matter how good a mod might be, if it's P2P it's not getting in the guide. Only time will tell if this will stick, but from the looks of things, EVERYONE is not happy about this; the people who use mods and the people who make them. So let's just hope that people don't jump on the bandwagoon for "Community DLC".
Bottom line: Don't buy mods, that's just stupid.
