escape12: I recently brought Myst masterpiece edition based on the praise it has received. After a few minutes of playing it, I realized that it wasn't my type of game.
The problem I'm having is not necessarily the game itself, but rather the option (or lack thereof) to refund it. Whereas Steam will gladly give your money back if you aren't satisfied with it, as far as I know the only way to get your money back is to contact GOG itself, and ONLY if the game has any technical problems. This is without going into law (I live in Australia), but in my opinion, this is unfriendly to the consumer.
There are actually two:
1. Technical problems that GOG can't solve.
2. You haven't downloaded the game yet. I used this refund option recently when I bought a game separetely, only to find out that if you buy another game (which I also meant to buy), you get that first game for free. I got a refund as store credit for the first game, then I bought the second game and got the first game for free as an extra.
In fact I think I once did get a refund for a game I had already downloaded (but not installed), when I explained the situation carefully to GOG staff. I bought the base edition of the newest X space game when I meant to buy the Complete Edition. I got a refund for my first purchase, then bought the version of the game I really meant to buy.
Anyways, as for your problem, I guess many of us see the current refund policy as an acceptable trade-off for the fact that we can buy our games DRM-free from the store. If one could always get a refund and still keep the downloaded game (as there is no DRM to prevent them from doing that), that doesn't kinda work.
Mind you, there are some DRM-free games also on Steam so in theory you could do the same there, ie. buy a game, copy the DRM-free game files to yourself, and then ask for a refund saying "Nah I didn't like the game". The thing is that if you keep doing that over and over again, Valve will probably stop accepting your returns at some point, or simply stop selling any more games to you, as they feel you are misusing the refund system.
So, yeah, I guess GOG could still implement that kind of refund system (which will be allowed "within reason" ie. GOG might still reject it in case they feel you are misusing the system), but I guess many GOG customers don't see that as a biggie.
If I buy a game I don't like, I mostly blame myself (for not reading reviews or doing my homework), or just simply "meh, ok, I don't like this game, next". To me personally the current refund policy is fine, giving me a refund for games that simply don't work, or if I've made an error in purchasing a game.
If you feel the ability to evaluate a game (by playing it) and still getting a refund afterwards is important, then I guess Steam is a better option for you, for now. Decisions, decisions...
