I am sure there have been many threads like this, and I understand it might be close to spamming, but since there's no other way to contact the developers, here is my version of it.
Congratulations on sticking with the game and congratulations on treating your client base the way you have treated them - us - since the launch of EWOM. When I prepurchased EWOM and shortly after, put it away at release, I could have never have guessed that 3 years later, I would spend a whole Sunday afternoon - and a good portion of the night causing me to droop at work the next day - with its successor, at no additional cost.
It wasn't that EWOM was unplayable or even unfinished. It was just a boring, bland game. The fact that SD acknowledged this as a deal breaker instead of saying "it runs, it plays, nothing to see here, move along" and decided to reimburse their clients in the best possible way, is a testament to the phrase of "putting one's money where one's mouth is".
I really hope your model of doing business keeps you in business, or even better, makes you an unprecedented financial success, just to prove to all the naysayers and "realists" that doing fair business is always good business.
