Spirit Games in Burton is top notch - the sheer amount of games new, old and obscure keeps me browsing for ages. In the middle of a whole load of AD&D and D&D 3.x stuff I found this tucked away:
It's the rules book from the boxed D&D game that TSR released in 1991. Just the rulebook, mind you, not the entire box. Which is a shame, because that would have been amazing. It's basically the rules from the Basic set all in one book so I now have a copy of the original rules that I miss so dearly, all for the bargain price of two English pounds. All that remains now is for me to win the Ebay auction for an original and complete redbox Basic D&D set and I'll be in hog heaven. That is, if hogs liked old roleplaying games.
