in my opinion, the original XXL2 had the best gameplay. OG has more refined gameplay elements but it only gets used maybe once in the whole game. And XXL 1 is pretty straight-forward and has basic puzzles and platforming segments that are extremely easy, even in the last Level. The combat gets progressively better tho. OG has by far the best fighting gameplay, but as mentioned earlier, theres only a few fights in this game and most you can just skip :/ XXL2 has more challenging puzzles, harder platforming and a better combat experience out of the 3
