I'm actually playing Adventure Island 3 right now, I played the others and if there is one thing to know about these games is they are HARD AS HELL, in the first game I actually found the levels looking ridiculously the same I died many times just because of confusion over what level it was.
Hello, @simonjay! Thanks for your comment... I'm glad to know that, I imagine you must have a nice time playing "Adventure Island 3", And if you are right, all the sagas are really difficult, to be honest I haven't played the third one, but what I can tell you is that "Adventure Island 1" is more difficult than "Adventure Island 2"... Still, it's a very good saga, "Adventure Island".
