Apparently, my work on SSS has not been unnoticed
, and I've been in contact with Firaxis for some time now.
Firaxis is offering me to buy all I did on SSS, ideas, source code, etc. They plan to abandon the expansion for CIV, and affect all their team on Civ V, that will be based on my ideas.
However, they offer only 200,000 $ for everything. What I dislike is they want to have the right to modify it as they want, and I have nothing to say.
I don't know if I'll accept... I'm not sure what they propose is worth losing my input to the game... Do you think I should ask for more? Can I go as far as 500,000 $?
