No limits for the creativity.

The theme should not limit my creativity. I like themes that does not contain any noun, adjective or a verb that is too specific - ❌ Zombie apocalypse - ❌ Skiing - ✅ Paradox - ✅ Life is a currency

Not too complicated, not too easy.

I like a theme that is a bit of a challenge when trying to come up with an interesting game idea, but in my opinion, trying to figure out what the game idea will be should not be longer than 3 hours, so the theme should not be too hard. But an easy theme is also not great. - ❌ Armor suit is a key feature - ❌ Impracticality - ✅ 20 seconds - ✅ Life is a currency

Should be a theme, that each person will interpret differently.

I think the game jam is about every person has his own idea, and it will not be fun when all the games will be the same. - ❌ 2D platformer - ❌ First person shooter - ✅ Paradox - ✅ One room
