Stating the obvious, the price point issue is entirely personal and subjective. From the dedicated hardcore who would pay almost anything to the lowballer looking for cheap, cheap; most of us wargamers fall somewhere in between. Let's face it, this is a game, a piece of entertainment. It is not a need but a luxury, and with that said it is only worth whatever someone is willing to pay for it, and a lot of us do have internal set, price limits. I do think valid comparisons can be made with other computer games and the dollar value they offer, though perhaps not directly.
The crux is not to lockout or alienate a majority of your potential market by setting the bar too high. For myself, I think value and too high a price were the determining factors in not purchasing BftB; a recent release where there was a fair outcry over the perceived excessive price. As a supporter of all of the developer's games up to that point, it came across as gouging for what in effect was simply a scenario pack with a few modifications to the engine. WitE is a 'new' game and quite unique, so doesn't suffer from that history and perhaps may command a higher price point. Personally, I don't think I have ever spent more than $60 on a computer game. I am a huge fan of Eastern Front warfare, including books or boardgames, so I am the intended market. I'm just not sure how much more I am willing to pay for the privilege of playing a game.
