Super Mario Bros. Wonder is exactly the thing that 2d mario series needed, classic mario levels and play with few new cool twists. Easy and enjoyable enough for everyone to play and absolutely hard enough to complete for any player. Almost all of the challenges are fair (except for the invisibility thingie that just plain sucks, minus half star you'll know what I mean if you 100 % this) and enjoyable to the end. The online play with people helping each other works wonderfully, I wish all online gaming had such supportive and friendly feeling.
