It is like where you live is a black hole that sucks all old gaming books into it.
Well, when it comes to some of the 2e books and boxed sets, I'm finding it fairly easy to find things I'm looking for. Yes, Whyte Knight has a lot, but the store doesn't have everything. (Trying to find 1e hardcovers or BECMI boxed sets and rulebooks isn't that easy, for example.)
So, when I came upon the Ravenloft stuff at Wizard's, I decided I needed to get as much of it as I can as fast as I can. (Four more, at least, to go.)
Wee Book Inn (WBI) is great, but I have to check each store at least once or twice a month to make sure I don't miss anything. (And then, I need to have the assets to acquire the best books.) The best game books in those stores come and go really fast!
For example, before I began this whole process, I noticed both the 1e Player's Handbook and the 1e Monster Manual II at one of the WBIs. I wasn't thinking I'd want them, at the time, but now I'm thinking it might have been a good idea to buy them. They disappeared quickly.
And just recently, the downtown store had (and possibly still does have) a copy of the 4e PHB. However, since I don't play 4e, I decided to go for the Dark*Matter Campaign Setting hardcover for Alternity instead. It was tempting, but I resisted. It will likely be gone the next time I go in there.
That store also has nearly a dozen Robotech books. Someone must have brought in their entire collection to WBI. That does happen sometimes. (Palladium books tend to sit and collect dust.)
Another example, Alhambra Books, another used book store just south of Whyte Avenue, currently has a BIG book for Champions (a core book, I think) and several books for Warhammer Fantasy Roleplay.
The owner just got the WH Fantasy Roleplay books, so I haven't really looked at them in detail. One of them is called Dwarf Lords, or something like that, and she's asking CAN $129 for it.
