MoltenFury is a RTS/Sim loosely based on Carrier Command from the Amiga days. You control a starting island, and need to invade the computer's islands/control zones. You can defend your control zones with defence emplacements, attack with tanks and fighter aircraft - or task your AI to do various missions. It conceptualises the idea that an alien race is invading Earth, but its war machine replicators can only create 20th century Earth-based hardware. I'm adding the concept of alien upgrades, such as time bombs and plasma/laser based weaponry to make it interesting. I'm working very strongly on the AI. Computer pilots actually fly the planes, land and attack etc. - they don't follow pre-programmed splines or actions etc.
Developed a basic tutorial system that enables a player to learn by doing. Uses eventing system so that actions in the game world tell the tutorial manager when actions have been completed.
