these guys are very underrated, they were huge in Venezuela, heck I remember going to the movie theater a couple of times as a kid with my dad and my uncle to watch their movies, I still watch their movies from time to time and they are still a blast to watch
A game that works like co-op God Hand with a slow, powerful partner? After watching the youtube video, that's what it made me think of... I could see that.
This! I was introduced to the awesomeness of Terence Hill and Bud Spencer during a summer in Austrailia as a kid. Loved them ever since. And this game, I would like to play.
First They must rescreen all their movies in 3D with a worldwide release just like Star Wars did.(and the movies with bud alone because we all know that he's the best of the two)
Then tons of tie in based on all the game genres you can apply to their movies.
