I discovered on my own the hidden merchant chest in Skyrim, the Dawnstar one as I was looking around for either flowers or ore. I also figured out the merchants restock if you save, hit them and then reload save. Both I imagine lots of people found out but these are the only two off of the top of my head

Scalebound looked like a really fun game and was the only Xbox exclusive and when it was cancelled that was the last straw that got me to move to PlayStation.
