Well saying the nemesis system wouldn’t have worked well in other games is almost assuming that it wouldn’t be changed or evolved to fit other genres. People forget that the real damage some patents/copyrights do is not in their explicit existence, it’s the sphere of influence they exert on related concepts entirely. We weren’t just robbed of the nemesis system, we were robbed of anything even slightly resembling it.

And I feel like once you understand that you realize it can be adapted to greater things. Spider Man games could have used it. Assassins creed would have been an amazing place for experimentation with those ideas. Could be adapted to Star Wars games, dragons dogma, yakuza, borderlands. And it doesn’t need to be a central focus of these games like it was with the WB games. But even the concept of having enemies that kill you be leveled up in some way is now tainted.
