PnP RPG Question

Hey guys, I'm trying to get together a list of the most popular and most sought after RPG books/systems. If you know of one that you've played or heard about or wanted to check out, please list it here. If you can post the company that puts it out that would be a big help as well.

To put it another way:
If there was a store that you could go to for all of your gaming needs, what RPG related materials would you like to see?

 

I've been looking for a long time for a rulebook for Steve Jackson's Car Wars game that came out in the late 80s. I have a lot of supplemental material for it, but I need the core crulebook to play it. I wonder if this post was helpful at all.

 

I think if a store like this existed, you should have a dark skinned white guy that is 6'2 with curly brown hair and is slighlty overweight with glasses and a bubbling personaltiy sometimes working there... I would go there if a store like that existed.. I'll let you know if I find someone that matches that description, hmm wait I may already know one...
