erm... maybe a stupid question... but even though the members of the tokamak team have iven upon it and won't be upgrading it... we can still use what they have left for us in comercial games freely, right?
I suppose so, but don't forget that if you run into some major bug that you can't find a workaround for you'll probably get stuck.
Tokamak in it's current state can be used for several things.
The "newtonian parts" are working ok, but the collision and collision response could have been better.
You could of course handle the collision and response yourself but that is very tricky to do.
