Obviously, tabletop roleplaying games support is our big Thing. I mean, we cover a lot of ground here to The Weirding, but the RPG section is one of which we are most proud, as well as the one on which we generally spend the most time and on which we put forth the most effort. And though we try to present materials and content which everyone who plays the games we cover can use, a lot of what we provide is dependent on previously published material contained in additional sourcebooks in the product line.
Dark Conspiracy is a great example. While you can use almost everything presented with just the basic rulesbook, the section really only comes to life if you have the Empathic Sourcebook (well, that or the second-edition rulesbooks, but I heard the printing and so on was just awful). Because the Empathic Sourcebook contains so much pertinent systematic information - information which includes rules addenda that covers a lot of the holes I was trying to cover with house rules - and I cannot legally reprint any of it, you really need it.
Of course, a lot of the books for these games have been out-of-print (OOP) for a decade or more, and they can be difficult to find. That's where ShopWiki comes in: it's basically a shopping search engine, which scours the Web for all listings of whatever it is you are looking for. You can see it in action by clicking the link above.
With ShopWiki, you can find literally anything you can think of, and you are guaranteed to find the best price, as ShopWiki returns every instance of the item it finds. No more searching through every shopping site you can think of and comparing prices the hard way; ShopWiki lists them all, along with the price, on a single returns page (or multiple pages, if apropos).
And they cover everything, not just books or games - coats and clothing, fashion accessories, movies and music, cooking utensils, baby strollers, adult diapers... ShopWiki is literally a shopping search engine, dedicated to finding whatever product(s) you are looking for, wherever it is available for purchase, across the entire Web. And because it can find anything anywhere, it is the perfect place to start your shopping.
You can enter specific search terms or check through their categories. I am not sure where you will find the RPG stuff, but I would start in Books and work my way out from there. And if you go there, you will notice ShopWiki even provides a handy list of websites which offer free books, book swapping programs, and more. It's very possible you could find whatever it is you are looking for for the low, low price of absolutely free!
Truly a great idea we collectors and roleplayers need to take advantage of every, single time we search for anything to buy. I saw where one of the gaming supplements I've had in my library for years, and never done more than flipped through, is going for darn near $100 these days! Who can afford that, these days?
