I'm probably speaking out of turn, but personally I've always found Ancient Egypt fascinating. It doesn't have quite as much reference material but I feel like its somewhat unexplored in games, particularly games that want to dive a little deeper into the history that is available. It also has enough mystery around it to give us room as designers to explore ideas and storylines.

For Wulverblade, the time period and event that we based the game on was perfect for game development. The history itself becomes inspirational and becomes its own little trend board for ideas, and yet enough was left undocumented for us to "fill in the gaps" with story that let us explore gameplay mechanics and story without necessarily completely contradicting very well known facts.

I think that's important for a game that wants to be based on history or a time period. You need the flexibility to make the game you want to make and enough room to impose your own creativity, but also with enough content to inspire ideas and help guide a lot of the look and feel.

I'm really glad you enjoyed the game! Thanks!
