Just like Super Smash Bros. made the Gamecube and N64 successful.
R-right guys?
Also if you think Bayoniche 2 and Xenoniche 2 are going to push consoles then you're deluding yourself.
Smash Bros. made the N64 and NGC successful consoles, it was the highest praised game of both systems because of how addictive it is to play, even still to this day Melee is considered the best of the trilogy.
Also, the delusional one here is you because if you were aware you'd know how people are angry that Bayonetta 2 is a Wii U exclusive and not coming to 360/PS3/PS4/XO that's customers who want it but aren't willing to buy it, well, they'll probably eventually.
In comparison to PS2 the NGC did lose but Smash Bros. Melee is its most played and popular game, after all, it's a fighting game with Nintendo characters that people love.
P.S.: About Xenoblade 2, have you seen that trailer of it that's on YouTube? You'd be lying to yourself if you didn't want to play that right now.
