I don't think I've ever paid more than $60 - and rarely that.
I'm happy to pay $60 for a game like Fallout 4 - definitely get my money's worth there and I want to support them in making more games like that.
Probably the most I've paid for a single game is World of Warcraft, but that's including all the expansions and monthly fees over the course of 10 years, got to be around $300 total, but again I got a ton of game time that money - and as soon as I ran out of content I cancelled the subscription and didn't start it up again until there was a new expansion out. Even then I usually wait for the prices to come down on the expansions.
Generally the stuff I collect is pretty cheap. I want a complete copy of Pa-Rappa the Rapper for PS1 but can't bring myself to pay $50+ for a used game.
The few special editions I've bought were well after launch and only because they were on sale. The mid-tier Halo that came in a tin (Halo 3, I think?) because it was actually cheaper than the standard edition at the time - I think you may have recommended that deal actually. Everyone wanted either the high-end one with all the crap, or just the game so no one bought that mid-level one.
I've also got the night-vision goggles that came with that one version of Call of Duty - but again, well after the fact, I think I paid somewhere from $25 to $40 for that set.
Many of the used games I buy on Amazon or Half.com cost less, often MUCH less, than the shipping fee.
Then again I'm not a "serious" collector - I don't buy stuff like Power Rangers for Sega CD just so I can never play it
