I say this as someone who thinks Wii gets more shit than it deserves. Had a lot of hidden gems even outside Nintendo's own games. I think it was a very good system. I also believe it's the very worst console of its generation. Simply because it's clunky as hell to use. Most of the motion stuff aged poorly. It's a lot easier just to turn a 360 and PS3 and play a game. I also believe HD twins had a wider range of games worth playing even if we ignore the AAA stuff.
N64
Gamecube
Wii
Worst consoles of their generation. Still very good systems. Tho I'm not the biggest Gamecube fan. I have not picked up a game for it in more years than I remember. PS2,Xbox and Dreamcast. I have.
Same story with N64 and Wii. At least 6 years since my last pick up for them. Saturn and PS1 often. 360 and PS3 often. In fact picked up sealed copies of Lolipop Chainsaw and Killer is Dead on 360 for cheap very recently.
Switch, however, while I do think it is not belonging in any traditional generation cycle. I could argue is the best system of the 8th gen. PS4 I also can make a case for. Both are just amazing systems.
