About releasing it for free, it would be an option if I found enough people interested in fixing some of the current problems and extending the engine with new features.
I would be very interest in something like this where those that use it give something back. we would all benefit form such a project. so many engines end up in the bit can because they don't have a community to support them. and as we all know the pascal gaming community isn't getting any bigger. perhaps if we all spent a little time working in the same direction instead of everyone doing there own thing. we could show the rest of the world that pascal is not dead and that it can hold its own in the gaming world. when was the last time you saw anyone asking for help on gamedev for a pascal game. even python is doing better and that is really pathetic.
