dis0rd3h: Ctrl + F Arx Fatalis, couldn't find it anywhere on the three days and the remaining games in the cycle.
Also beginning to notice the game (probably, at least AFAIK) never goes on sale, not here nor on Steam. Anyone knows why?
Arx Fatalis never goes on sale anywhere. I imagine anyone's guess is as good as anyone else's guess as to why. I can't see a company posting in a forum "oh, we don't put it on sale because (we're greedy|we don't care|<insert some other reason that no matter how rational it might be people will react negatively in some manner, boycott them or otherwise cause the company a risky PR situation), so nobody is likely to ever know why with absolute certainty. Could be a legal agreement that binds them to a certain minimum price, or could require multiple parties to agree to something while one party refuses to even discuss or negotiate. Could be that it's so unimportant to them that they have bigger fish to fry, or it could simply be one of several potential pricing business models they have chosen for the game.
id Software games for example are usually never cheaper than $5 each no matter how old they are, although some of the older titles occasionally dip down to $3.75 or so. Some companies value their works at a certain minimum price and would rather sell few or zero copies than accept lowering the price and devaluing their assets. Some would rather remove the product off the market if it can't get a certain price or higher, then create a shortage and reintroduce it several years later at a higher price in the enhanced edition or "remaster" or similar.
Write down any viable theory on little bits of paper, pin them to a dart board and throw a dart at it... there, that's why! :)
