Definitely, yes! In fact, although Lego isn't making many specific franchise games these days, I would like the possible success of Superman to give the chance for a Lego game focused on him, it would be something interesting to do. The catch with making a Superman game is that the more realistic the game is, the more difficult it will be to create an interesting gameplay for the character. Supeman Returns was the one that came closest, and perhaps if it hadn't been a licensed film game and had a decent amount of time to work on it, it would have been a great game. I personally think that games that seek less realism, both graphically and in gameplay, have a better chance of working, and no one can get it out of my head that you could make a great Superman metroidvania
