super mario galaxy of course. i have played a ton of platform games through time, all the marios, all the jak and daxters, vexx, prince of persias, etc.
i think galaxy is possibly the toughest, and definitely the most creative. i think they have increased the difficulty to a high level.
ive gotten all 105 of the first stars and have beaten bowser. i started on the purple comet missions. i am on the 4th one and i must say they are getting pretty hard. i have had to repeat many things and am very impressed with their ideas.
for those that have played what do you think? how hard is it compared to other platformers?
