There's a Nintendo World Championship cart for sale on eBay going for $100k+ US. It made me think - what is the most you have ever spent on a single video game? Also, if you wanted a rare game enough, how much would you spend on it to buy it?
For me, the most I've spent was $70 for Texas Chainsaw Massacre(Atari 2600). I know it's not much more than new games today, but most people just see it as a 30 year old hunk of plastic. As for how much I would spend on a game - maybe $150 to $200 if I really wanted it.
