Don't get mad just cancel your pre-orders
The truth of the matter is a large percentage of your user base were unsure as to whether to buy Notum Wars or not - by the looks of it a lot of us including me gave you the benefit of the doubt and tried to support you.
The whole concept of charging for a patch hasn’t gone down well with your customers and now to top it off you have managed to totally screw up the release for almost all your customer.
I personally am not going to shout and say it’s unfair all I’m going to do is cancel my pre-order and not bother. I may buy it in a few months when Game is selling it at a knock down price due to poor sales but now I’m in no hurry, why should I be. You can carry on supporting 2 versions of your game (Notum patch and the normal) and all the cost associated and be sure of the fact that I won’t even waste my time pre-ordering and cancelling come the next “buy” patch.
