Fair enough, except this is quote is taken from Steam page:
"Inspired by our previous award-winning title Aggressors: Ancient Rome..."
If you want my two cents, I imagine Slitherine owns the rights to the Aggressors
IP but now the developers want to strike out on their own. Perhaps they're still obligated to work on Aggressors
, or perhaps they just wanted a fresh start (or maybe not all of the development team have switched to Kube) but for whatever reason they also decide to found a new studio when starting Imperiums.
Either way, our point stands as it's clearly enough of the same team to be able to claim Aggressors
was their last game.
