Sales=/=Popularity

In most cases yes of course but its not always correct. Example LoZ is more popular than Luigi's Mansion.

thats because zelda as a franchise, sells more. 

Luigi's mansion is a Mario Spinoff which is more popular than anything. You think Luigi's Mansion would've sold close to what it has if it wasn't attached to the Mario franchise?

More popular-> more sales.

Give me a better example. Unless you mean more popular only in a certain demographic (e.g. internet people).

I know but according to him the game that sells the closets to 2mil next is the most popular franchise ;-D

thats because sales is a direct indicator of popularity. 

Superman logo is the thrid most recognizable logo in the world. Everyone knows Superman is. If there was a superman game it would sell billions, right? Because popularity = sales, right?

Ummm... your post has a whole in it. If that were the case wouldn't Paper Mario/Mario+Luigi RPG/etc sell more than Luigi's Mansion? Especially when Luigi's Mansion is completely different type of game than usual?

(not disagreeing that Luigi in it didnt help of course)

Anywayz, its still a good point, your closest to 2mil in sales is a bit silly :/

I think a lot of JRPG series... Ys, Persona, Disgaea, Tales of are all seemingly very popular on the internet, but don't really sell a lot. It's the issue with the internet being so full of vocal minorities.

Persona or Xenoblade series in general come to mind. The Souls series is another. Lost Odyssey. I bet Bloodborne (although I guess still technically a Souls game in design) will be.

I suppose given number of titles Persona would take the cake. And that cake won't bake so voila!

No, its a major factor but its not the entire formula.

Edit: A_C_E Post makes sense^^^
