Hey folks! I thought it might be fun to brainstorm some ideas for the 10 shortlisted themes! You may not want to give away THAT special idea, of course, but maybe you have some sharable ideas for other themes?
I'll go first, and I'll fry the brain on my personal favourite of the 10, "Start small":
City-builder type game where you start with a single builder, and one or two types of buildings. Build a small village, attract traders, and eventually get new types of building and make a city. Potentially a game without wars (although maybe criminals), just focussing on building a city.
Instead of a city, you are a tiny tribe, and you must keep moving to harvest new areas and explore the wilderness. Perhaps you'll discover some ancient ruins with mystical powers, or run into the hiding place of a particularly dangerous animal? Or you'll discover a marketplace or even a city, and trade some rare goods that you can then use or trade with others in a different place?
War-game. Perhaps like Risk, or turn-based like Heroes of Might and Magic or even a RTS - start with a few creatures, expand and recruit to take on enemies and unexplored areas. Convince all to yield with your sword and axe.
Some kind of Tower Defense game, potentially as a city where you can add defenses as you defeat invaders and earn more gold. Start with a couple of archers and gradually build stronger and deadlier defenses!
