I'd vote for a medieval type game maybe featuring a wizard's tampering with dark forces opening a portal for a demon assault, armed with swords, axes, crossbows, etc, you have to try to survive the demon hordes and build a fortress, look for survivors, farmers, smiths, furriers, other knights for bodyguards, or heirs, that you can switch between and level them up, maybe each with their own special ability, so death doesn't mean a complete loss, etc. Eventually you bring the fight to them and take down every demon encampment you see, until you reach the portal and close it, then you have to do cleanup of the remaining demon hordes. Something like that.
Either way, I think the team has done a great job and i commend their persistence in delivering this game through setbacks, and upheavals from the community.
