lazydog: My particular stance?
I bought dying light at full price about two weeks before it went 60% off in the latest sale. I wont be bothering gog for a refund so I can buy it again for less, because I was prepared to pay the asking price at the time. Also, it will not go against me if in the future I may have an actual real issue with requiring a refund- for example the software does not work etc.
Each of us have a stance I guess, and I am mostly the same as you, but perhaps for different reasons, and I fully understand someone feeling hard done by.
I've certainly felt hard done by on occasion, but for me it is often about the effort to do anything about it, and GOG have enough to cope with, so for the sake a of a few dollars I just tolerate the situation.
I can honestly say, that sometimes I have paid more for a game than I really wanted, but felt between a rock and a hard place. Obviously that wouldn't be for a game I don't care a lot about. But sometimes I have paid more than I should have. Yes, it was a conscious decision on my part, but as customers we can be taken advantage of.
Dying Light is a perfect example, where I have now paid more for the game overall, than I ever would have been prepared to pay in one hit. I have resisted buying some of the DLCs, but some give good enhancements, and so they feel a must. I am still waiting for some to reduce enough in price, but each additional one I buy makes me grit my teeth. I feel like I have been taken advantage of. It's the perfect example of being lured into something, and then once you are committed you feel compelled to continue. I never saw it developing to the extent it has with DLCs. It's not that easy to pretend they don't exist ... and I waited ages to buy the base game for what I thought was a fair price.
P.S. Part of the problem, is that unlike Steam mostly, there is no guarantee that any game (a few exceptions) is still going to be around at GOG in a month or three months etc, including DLCs. And of course the DLCs are rarely interchangeable between Steam and GOG versions of a game, and at GOG at least, you have to own the game here, to obtain any DLC for it.
