Just thought I'd post one up about Skyrim, so people can give tips loopholes etc.
If you are going to put anything that may be a spoiler please use the NSFW button!
If you crouch and shoot shadowmere repeatedly this will get your archery and sneaking right up and level you at the same time! Incredibly boring though, I didn't bother
Also if you pay for training, try making the character a follower first, then you can trade the money back off them!
I would avoid marrying Camilla Valerius (I had to use the console commands to undo it) as she is a dirty cheating skank and is already in a love triangle!
If you marry Mjol The Lioness her mate is always hanging around at your house (if that's where you choose to live) - if this bugs you you can kill him, but not infront of her as you will not be able to trade with her or get your daily money! Follow him out of the town and make sure no-one sees you do it, then take him out. I havent tried it, but presumably there would be no problem with doing it in Beast form if you happen to be a wearwolf, provided no one saw you transform
