So I thought how big a budget do they actually get? Then I googled this list:
Since 300k GBP are (about) 10% of what the private investor is putting there and since they will get about 1.2m GBP on Kickstarter and through Paypal (and of course Kickstarter and Amazon take about 5% of the raised money, Paypal also takes about 5% of each transaction), their budget should be approximately 4.2m GBP (I should also subtract the money they will spend on the swords and other goodies, but this goes into “marketing costs” which are part of those costs in the wikipedia list) which makes about 6.7m USD making it the 30th most expensive game.
Of course, the list is very extremal, the difference between the 1st and 7th place, for instance, is over 200m USD. And more money does not necessarily mean better quality (some of the very expensive games at the top of the list are good, but not all of them). Still, if the wikipedia list is correct (which is not all that clear given that “issues” box above it), it seems that Warhorse will have not have to worry about making too many compromises budget-wise and that’s good.
