Is it against pricing theory though? Would not a completed product upon release be at its highest value? Would that not be the best chance to maximize revenue? Rimworld had a similar price increase on release. Did sales suffer? Did Parkitect suffer for raising the release price? I do not know if that is the case or not but it would seem to me that the release price should be the peak price. Perhaps I am unfamiliar with the pricing theory you are espousing.
Either way the game is well worth it if that style of game appeals to you. IMO it has never been done better and I am greatly looking forward to the campaign, tech tree and all sorts of other goodies.
