I don't know of any company, or at least smaller companies, that can afford to give multi-thousand refunds to people every day. Obviously they are in business to sell stuff, not give the money back.
I guess this is just a case of the game taking too long. People lose interest, and without a game to give them they rightfully will ask for their money back.
When Full Throttle was developed, Andrew at the time took no pre-orders for it till the game was done. I had been emailing with him during its development, waiting for new details, wanting to see it, but there was nothing for me to order or pre-order until the big Pinball News reveal. I actually was impressed with the lack of crowd funding and that attracted me to his business. Then he took orders, me being at the front of the pack, and it still took longer to deliver to me than expected but I had it in a reasonable time.
I'm not sure if ALL the blame can be thrown at Fox's feet on the 2 year delay. Could they have released a game with the old cpu and pre-rendered videos and called it a day? Would we better with an Alien that is "less than" the one that came out, but got it a year ago, and be talking about Heighway 3 or 4 at this time?
Monday morning quarterback I realize. At this point the game exists, and I hope the hump can be dealt with to start pumping them out.
