As we keep saying, the �599 option is for commercial enterprises over a 10 year period. This comes out to �59 per year, and only companies that turn over �200,000 in that 10 year period need to buy this license.
Everyone else can go for the cheaper option. I really think keeping quoting the $1k figure is a slightly unfair comparison and can mislead our users because hardly any of them will qualify for that license, everyone else gets it on the cheaper license.
If a company is turning over �20k per year, then they will probably want to pick the most stable, best supported and future proofed piece of software out there. If they think those qualities are more with a competitor, this is fine! We believe however our product will be far superior, that's the ethic we are building it to.
�59 into a �20,000 budget really isn't much for a company that is earning a living as a direct result of our product (remember the license states that �20k turnover is for associated revenue derived from using our products). If a company earning this much really is debating as to the benefits of using different products solely because it saves them �40 a year, then good luck to them!
With the discount license, you can still sell your games as long as your revenue doesn't exceed �20,000 per year. That is the only difference between the commercial license and discount license.
