The problem is that PI are no longer developing these small games with the use of 1 or 2 developers ... they have designers, QA people, graphics people, developers etc. .... and I think 7 full-time people is a good estimate (might be 4 or 5 full-time and some ad hoc though). In Denmark it is considered that a software developer costs around 1 mill. DKK a year in salary and infrastructure. Which is what I based the estimate on. I am assuming the prices for swedish developers are the same.
Doing it for $250K would mean that Johan is doing it alone (again), which I highly doubt will happen. IF they decide to make CK2, they would want to do it right and invest heavily in the development like they are currently doing with Vicky2.
So I think it will all depend on how V2 sales go .... if it makes a profit, I am sure they will do CK2 at some point, as I think that has better selling potential.
