Egyptian culture is not the issue, it was something in relation to tying your stargate to Egyptian concepts of alien influence. The Stargate name isn’t copyright because its actually again mentioned as alien technology (hence the film/book was even written). But its how the wormholes and stargate are shown on screen which was the no go. Again stripping the 9 chevrons no moving ring no strange watery effect then its possibly ok. I just found that once you’d striped the content which makes it cool (Stargate) then its no longer particularly cool.
There is/was a team working on a Stargate game, experience. I’ve not seen many updates and I think they also had a tough time even getting a response from MGM.
Comic books have really started up because MGM tried to suck the last chunks of money out of the franchise before they rebooted it. A game is far more permanent and can disrupt or distract from the new cannon.
Again not trying to put a downer on your work, was just highlighting the issues I’ve had researching Stargate fan content.
