DrIstvaan: Mikee stated in
an earlier post that they're not trying to compete with others on grounds of low prices; if they can offer something for less than the others, all the better, but it's not a central question for them.
He also said
they are aware of the advantages of more price points, but are not going to change the system (the stability/predictability of which is /thus, you know exaclty what prices to expect from the service/,
in his opinion, one of the best features of GOG) in the near future.
EDIT: Added links
Thanks for the links. I can see the reasoning. They use price points to get simple and stable prices. However it hurts their flexibility and especially for collections they are not competitive right now (see examples in my previous post). They say, its not only price but also quality but for these old, classic games its always kind of the same product, isn't it? For my examples (X-Com complete pack, AoW trilogy) there is probably no difference in quality, whereever you buy. So, price remains a strong competitive factor.
With the proposed permanent discount on bundles in my post earlier, they don't need new price points but could stay competitive, maybe even increase turnover.
Of course its up to them, customers will for sure also look after price when buying. So we will see, who has got the best business model in the end. :)
