Kraftwerk,
Even if I don't share your bad words against the devs, I have to agree that I would like a price reduction too. My friends would better like to buy the game and we could organize MP games together sometimes (and the 2 of them playing WoW would probably get detoxified

). Even if Sombre evenly pointed up the reason for the different cost of indy games, I must say that the opportunity-cost of a game going for 3 years old and still costing around 45/50 euros is not little. Here in Italy, but surely everywhere, every month 4/5 magazines of pc gaming come out - they cost 6/7 euros each, they give you a complete game of 2 or even 1 year ago (and one of the "big pieces"), all the new demos and patches and mods, and come of course with the magazine itself with many interesting news about the gaming world. That just to talk about the opportunity cost of this game.
Having said that... I can't complain a lot against whoever decides the price. The devs put a lot of love in this game - a kind of passion that you don't find in many games from the bigger companies. Lots of new patches, and enough free new contents with every patch that many companies would have asked you another 20/30 euros for "the expansion". The game also comes with a 300 pages manual which surely they don't print for free, and well, even after 2+ years, it is always the same nonetheless.
And another thing. This game is huge. You could probably play it... dunno, 6, 7 years? with it without getting bored, if it's your genre (and it is my genre, for example). Many so-called "masterpieces" today maybe come at 50 euros, 30/20 euros if you wait some months, but longevity=10/15 hours=one week or so for me, surely less for many gamers.
So, it is difficult to judge. The game has its reasons (free support with new contents and patches, great and nice manual, virtually almost endless longevity) to have the actual price. A price reduction, on the other hand, would be very appreciated now that many of the long-time fans have bought the game and shown their support to our dear Shrapnel, as other people, less likely to spend 50 euros on an indy niche game, would probably get attracted by a lower price and give it at least a try.
P.S. None gets offended please, I tried to show comprehension with everybody's ideas while bringing my ones, and I am opened to new points.
