But the biggest selling point of this is access to your content from the previous generation. I think that's that part you're missing.

how can people be so stupid?

the Wii, at the time, sold FAR better than Xbox 360 and PS3, and yet still barely made more numbers. This time around the WiiU is the lowest selling console.

And DLC is where they made all their money, and Wii DLC sales were puny in comparison.

There's no logical reason to make the game on WiiU, the cost to benefit ratio is just not there.

As if this is a costly game to make lol.
More like a cheap budget game that should be sold for €10.

By that logic, shouldn't all 3DS games be under $20 given they're practically below GameCube in tech and really cheap to make?

Still more expensive than a RB game.

The same team that made FE: A is making the new one. That's a development cycle of around 3 years.

A game can have a development cycle of 10 years, if only 3 people are making it, that doesn't mean the budget is anywhere near the same as a game with a 1 year dev cycle and 250 staff :p

Fire Emblem has no licensing, so even with a 3 year dev cycle, probably costs far less than any iteration of Rock Band.

Then nintendo shouldn't make any mario/zelda/metroid/dk... for wii u, since it's retrocompatible and wii already have games of those franchises.

Do you understand how ridiculous that sounds? This is a new game. the wii games won't make any more money.

Installed based won't matter much in this case. sales may be lower, but nowhere close to the installed base ratio.

"And DLC is where they made all their money" And...? you know that wii u can have dlc just like any console right?

There is no logical reason to skip wii u.

Nintendo console users tend to not have quite the same interest in DLC as PS and XB users.  we all know WiiU can have DLC, some of the best DLC is on that system (New Super Luigi U and MArio KArt 8 DLC), but DLC wasn't nearly as prolific on eShop as it was on PSN and XBL. 

And as for Samus over there, HAH!  I LAUGH AT YOUR IGNORANCE! "Oh, this game is cheap to make and shouldn't cost more than 10 bucks!"  

Licensing, bro.  Are you familiar with the term?  Like 3/4 of that game's budget goes towards getting the rights to each and every song they put on disc. When you're getting popular music by some of the world's most popular and successful artists, that shit isn't cheap.  Sure, we COULD all just play homemade songs like Guitar HEro's creator, and we can certainly get stuff that's all indie and therefore cheap, but who would buy that?  NOBODY!  

Just, damn. Seriously, Look up the Dunning-Kreuger Effect. The less you know about something, the more likely you are to believe in and perpetuate false information about it.  

It has a lot of success in conventions and a café i know of still organize a rock band night once per month, so i guess there is still an audience for plastic instruments.

I wonder who they are though.
