A fun Mario game that asks a lot from you to conquer it.
I had a lot of fun collecting the coins in all the levels and feeling like I was completing the whole game, until I looked at a guide and saw that to fully complete the game you have to do a TON of stuff. Get all coins in each level without using a golden leaf or P-wings. Get a golden flag at the end of every level. Pass all levels with Mario and Luigi. That stuff combined is probably 40 or more hours of game-play depending on your skill level and believe me this game can get really HARD!
BEST MOMENT: The final boss fight, the best in all the Mario games I've played. Wow, it's really epic.
WORST MOMENT: All the Cosmic Mario levels. They really suck and they overdid them towards the end.
FINAL JUDGEMENT: I would suggest buying this game if you want to complete everything. I felt rushed on this because I rented it. You just need a lot of time and patience to get everything. If you just play casually though, you'll find it very enjoyable.
