The Legend of Zelda: Skyward Sword was my last Wii purchase and The Legend of Zelda: Breath of the Wild was my last Wii U purchase. Let's hope the next Zelda will come out before the end of the Switch's lifetime.

I suspect Twilight Princess was a lot of people's last Gamecube game too.

Xenoblade Chronicles. It was so amazing.

The moral of the story:
Live by Zelda; Die by Zelda.

Every good console library needs to be sandwiched between two slices of Zelda.  

I will say that, in the case of the Wii at least, I'm glad I didn't stop with Zelda, as then I would've missed out on awesome games like The Last Story and Project Zero 2 which I really enjoyed.

So a good console is a Zelda sandwich? I can support this stance. Great Zelda games are a big pro. Although I'm not averse if the sandwich gets some good topping after the second Zelda, like the Wii (the one we discuss here) got with Project Zero, Xenoblade and Pandoras Tower.

I can agree to that.    Mainly, a Nintendo console needs 2 Zeldas though, one near the beginning and one near the end.  Wii U only had one Zelda, released right when they decided to pull it off the shelves.  Sadly, the SNES, which actually was a good console, only had one Zelda also.  It was, importantly, during the first year of the console, but I think the SNES would still have better if it had a second Zelda.

Don't forget The Last Story. ;)
