I don't buy the niche argument. Not all wargamers are interested in all wargames. There are a few games I would pay $100 for, many more I would pay $30 for, many wargames I would happily buy for $10, and a few I would only buy if they sold for $1.
That makes the assumption that everyone thinks the same game is worth $100. I may be willing to pay $100 for game A but only $20 for game B even on day 1. One difficulty with wargamers is that we're not all the same otherwise your approach might work. We saw the uproar when Amazon blatantly priced goods based on a buyer's history, it didn't go over well even if they certainly do a similar thing today less blatantly.
As for digital downloads being almost all profit... Don't forget royalties/contractual fees that must be paid for licensing, costs to support the users that buy the cheap copies and dilute the potential for higher capability support to the users that paid more, infrastructure costs,... Bundling them into a generic "almost all profit" is a stretch.
