Pokemon. I love Pokemon, and I think the games and design have become better over the years, but it's just not unique enough to justify the cancellation of the other series listed. --- Baseless prediction as of 01/04/13 : the next Xbox will be called the Xbox On.
Of the series I play, Pokemon. I've played all of those series except Metroid, so I won't consider it to vote.
Mario is my favorite series, Zelda is probably second, and Smash Bros is too fun to get rid of. Pokemon used to be fun for me, but now I just find it tedious and boring. I don't even bother playing anymore and won't be sad if they stop making games. --- Welcome to the world, M.J.C. July 13, 2012
As much as I hate to say it... Metroid. The first four are the franchises the casual fanbase are familiar with the most and any of them being lost would deal a lot of damage to Nintendo. Metroid however is not that popular to the casuals and losing it would still deal some damage, just not to the extent of the first four. --- 3DS Friend Code: 3179-6117-3933 PSN: ansonip2000 Official Take-Mikazuchi of the Shin Megami Tensei IV board.
Metroid, considering i've gone years without it already. While it would be missed I can go without Metroid compared to the other 4 choices. --- NNID: Illuminatis Current Systems: PSP, PS3, Wii, WiiU, DS, 3DS
It hurts to see that so many people liked Metroid the least of those Nintendo series. I thought for sure that Pokemon would be getting lots of well deserved hate. --- Want Luigi's Mansion: Dark Moon, Rayman Legends, and Bioshock Infinite. i7-2670qm @ 2.2ghz | 6GB DDR3 | 1GB Geforce 540m
