Obviously you are pretty damn good at your job so don't take this as me 'questioning you' but rather just asking a question (if that makes sense), but I wonder if that might not backfire.
Paradox are known for producing deep strategy games, taken seriously as the most hardcore company in the genre by a mile. Most of the fans (judging by the forum) are fairly well-educated, middle class men college age and upwards. Johan has posted where FtM sales come from and it's overwhelmingly people from very rich countries buying the Clausewitz games. All in all, I'm not sure price is a huge issue for these fans. In fact, for these type of people, who weren't familiar with the company, there could be a risk that they might dismiss a game because of a cheap price. I can imagine myself looking through GamersGate's strategy section, upon seeing a game priced €15 and thinking "that can't be a serious, deep strategy game, they cost a bit more than that". So I suspect this new pricing scale probably won't make much money from existing fans and that demographic in general.
Conversely, I'm not sure it will lure in a whole load of new fans, because the Clausewitz range of games (IMO) are not something your average casual gamer is going to buy just because they are a fairly cheap price. I think people who are browsing GG looking for something cheap enough are probably not going to buy a deep strategy game just because of the price. EU3, Victoria and HoI are games you play over a period of weeks, even months. Starting a game of one is a big commitment! I'm just not sure that demographic is going to buy your (I nearly typed 'our', haha) Clausewitz games based on price.
Anyway, I hope this doesn't come off as a patronising lecture from an amateur using nothing but guesswork, I'm just curious as to how this sort of thing works and putting forward my observations.
