It’s a good time to be a PC gamer, this is a good move for Square Enix. I really like how even games from decades ago are still playable and very affordable. There’s a big market for quality single player RPGs as evidenced by the success of Baldurs Gate 3 and Persona 5 Royal.
Bravo. You took the unique thing about the setting and character and made it into unique gameplay elements that fit the theme and sounds like fun. Superman’s dilemma is not being able to stop everything despite his power and the rules of the game tell that story. I think you’d be a good game designer if you aren’t already. The only thing I can think to add is maybe Kryptonite makes him have a health bar and diminished powers for a while, so he has to turn from the cat into the mouse for a little while until it wears off, kind of like stars in GTA.
What Wario game are you referring to? I haven’t owned a Nintendo system in a long time.
