this game is probably the only reason i purchased a wii! and it was worth it! 1, 2, 3, 4 player, its all good! we love all hooking up our remotes and playing together on the same screen. its really great for younger players as they dont need to wait their turn- i used to hate that when i was little! whats more, you can carry one another across difficult parts, put yourself in a bubble while another player completes a part, or when you have yoshi, you can hold another player in your mouth- we have great fun with that one! i love the return of yoshi, the battle ship, and loads of other things from previous marios. im a diehard mario fan, and this game has lived up to my expectations. very like the ds game, but with whole different worlds to complete. its packed with exciting stuff, and just when you think its all over or you have completed a world, something else pops up. there are so many times i though i had done it, got excited, and then quite sad that it was over, and then a whole new world appears! brilliant! they have also given a purpose to collecting all 3 star coins on every level. and if your really stuck, luigi completes the level for you if you want him to. helicopter mario and penguin mario are brilliant additions, i do wish they had kept the mega mushroom for the wii game though. and i miss being able to save an item and use it in the middle of a level- but im willing to sacrifice that for the fact that you can collect up to 99 of each of your items and keep them in your item store! the graphics and maps are outstanding! especially world 6 when the map is working up a big mountain. a fantastic game, which doesnt compare to any other mario game for the wii. must must must buy, worth every penny as even when you have completed it, you will still play it. the coin battle section is great too, as you can compete against other players, still on the same screen. buy it! no wii should be without it!
