9. Super Smash Bros. Brawl
The Super Smash Bros. series is known for its frantic four-player skirmishes and glut of Nintendo all-stars to do battle with. It's a series that began on the Nintendo 64, found its footing on the GameCube and, unfortunately, stumbled somewhat on the Wii.
While it offers tonnes of fun, Smash Bros. Brawl had a smattering of annoying mechanics and a very lengthy development time that would have fans believe it would be far superior to Melee. Where Melee was precise in its gameplay, well presented with its UI and wielded the same level of staying power as Nintendo themselves, Brawl placed higher emphasis on the casual player, and hardcore veterans of the series took issue with the new design approach.
The consensus by many is that if the development cycle and delayed release of Brawl was drastically shortened, many wouldn't have found the title disappointing. With time comes expectations, and Nintendo simply couldn't reach them once they had skyrocketed past realistic.
Smash Bros, in any of its iterations, is always going to provide a fun night in for friends and family alike, as its gameplay formula is one that simply doesn't age. If the series does have a blemish on its resume, however, most believe it came on the Wii.
