Definitely the psx era. I grew up playing all those great rpgs like final fantasy, legend of legaia, legend of mana, and so many more. My main inspiration is final fantasy tactics, I'll be implementing a similar "job" system, but with a twist. In hex you'll find gems that allow you to absorb mana and cast, and also follow a special generated skilltree inherent to the gem.

However, I'm focusing on making a fun cooperative/competitive multiplayer experience so even though Hex is inspired and takes systems from those games, it aims to be an entirely new genre. My goal is to make truly dynamic procedural content and a unique play experience for each player and each character you play.
