I can't get bad industrial meal at McDonalds for £9.99 ? Ok
Fences as a very raisonnable price, no problem! Perfect to gain new customers but discount for people buying previous 3 versions is a joke...
Just like every other business on this planet, When overall sales go down the loyal customers pickup the tab with price increases. Large price increases is always a sign of a company struggling financially. Its also unique for a developer to release a beta and charge for it.. Another possible sign of struggle.
