The only RPGs I’ve ever spent more than a cumulative $100 (CAD) on:

– WFRP 3rd Ed.
– Kult: Divinity Lost
– Unknown Armies 3rd Ed.
– D&D 4th Ed., but only if you count minis too

These are very special circumstances – usually I don’t exceed $30 – $40 for a print copy or $20 for a PDF. It was a close call with Coriolis but the price point stopped me in the end. I try pretty hard to run on fumes as much as possible at conventions, too. I’m pretty frugal with my hobbies.

Edit: The above is technically correct, but also I suppose I’ve spent considerably more than 1000 SEK cumulative on Vampire: the Masquerade. Probably more than 2000 SEK if you count makeup.
