Mori_Yuki: I guess I got to clarify some things here. I'm not saying that OP got an absolute right to receive a refund. GOG grants him the right to
request one which he has obviously made use of. Based on their
policy there is no restriction in any way, shape, or form - implicit or explicit - not allowing to play for whatever amount of time.
...
GOG can very well reject the request but would
that be fair? If they don't react in a timely manner, refund requests taking weeks to be processed, whose to blame?
I don't want to keep harking on about this, so all I'd say here is that while there isn't an explicit restriction on play time, the first clause in the policy says that if it's using the policy in a way to hurt developers, then GoG can reject it. It's also a voluntary, not statutory refund policy.
Now, that means that they basically reserve the right to look at whatever they want when they look at a refund (with an added proviso of ensuring it's not against local law). I believe that GoG would be very justified in refusing to refund in a case where the "customer" has played this long and got all those achievements.
Regarding the issue of playing after requesting the refund, that goes to intent on the part of the claimant. It actively undermines their request for a refund - i.e. you could interpret that as being a cancellation of the refund request (by actively continuing to use the product). Again, I think it would be fair for GoG to refuse to refund in this case.
I agree that to stop scammers, GoG should probably tighten it's refund criteria and make it clear that you must stop playing immediately upon issuing a refund request - but that would also mean that the freedoms of the many are being restricted by the selfish few who have abused the system.
