It is far more important to me to show confidence in my vision and to let other people learn from what I've done. In my view a lot more games should be open source, because far too much of the process is hidden behind mysticism, with far too many people wasting a ton of time reinventing things from scratch.
And, well, finally, I'd ultimately like to make everything I do available for free, anyhow. The only reason I'm selling Kandria is because there is no UBI in this country and probably won't be for many years to come, so I have to fund things somehow.
I'm personally sceptical that it's healthy to be this caged about things, but I don't have any numbers to back this up -- though I suspect nobody else does either, given how marketing is always just a crapshoot.
