OldOldGamer: My guess is that PoE, is too pricey, even at 50%.
The full-gadgets edition are priced to something like theft.
What do you think?
There will always be people who find the price of any particular game as being too expensive for their own expectations/value/judgment/economic conditions etc. of course. More realistically though games are priced exactly at what the marketplace values them at as a whole. If a game is truly overpriced compared to what the entire target audience thinks it is worth then it wont sell very well, and the publisher wont bring in the bacon. If that happens and they want the product to be profitable then they end up needing to lower the price to boost interest and stimulate consumer interest. No matter what a game's initial market price is they all go through this process and eventually the number of people buying it at the initial asking price drops. They use sales to re-stimulate interest in the game, but the regular price remains the same until even the sales promotions do not result in enough revenue generation and they're forced to lower the base retail price. They'll continue to drop the price over time to maximize revenue at whatever interest level remains, and most games reach a minimum plateau level beyond which they wont drop the price any further.
Highly successful major AAA titles seem to hold their higher prices the longest, some never dropping the initial asking price for years on end. Others do well but interest slowly declines over time and they end up dropping the prices. The same is true with indie games of course too, although their initial asking prices tend to be lower than games from bigger shops. Ultimately though pricing is set based on predicted interest in a given title, and then adjusted afterward based on how well the game makes money and that's affected by how well it is received by gamers.
What I've found is that if a game seems to be greatly overpriced, it is a matter of individual perception only, because it is the wider marketplace that ultimately decides what a game is worth in terms of price. If a game is high priced for a long period of time, then it must be selling very well and the publisher has no compelling reason to lower the base retail price.
With respect to Pillars of Eternity, there is a huge cult market for Dungeons and Dragons style games out there, in particular right here on GOG. It is rare for games of that style and size/completeness to be produced nowadays, so when one comes along the die hard D&D enthusiasts among us trip over ourselves to grab it up, whether buying it full-retail or when seasonal sales etc. come up.
As long as there is high level interest in the game however, I wouldn't expect the base asking price to drop much at all. Base prices only drop when consumer interest drops, so if a game is keeping a higher price than one expects then it is most likely because the rest of the gaming marketplace puts high value on that game and are buying it up in sufficient quantities to confirm the asking price is both reasonable and profitable. This is good too because it increases the likelihood that such companies will produce sequels and other similar products in the future, as well as potentially stimulating other companies to follow suit (such as Tides of Numenara for example).
Anyhow, this may be stating the obvious but then well... sometimes the obvious needs to be stated too. :oP
