I never really got the complaint about the whole holding hands thing.
I mean...I played FE for 12 hours straight and the only thing that hurt was my brain (which happens to everyone who plays games for too long per day)
On that note, it seems a lot of people really like Dream Team, and considering how the guy at my Gamestop said that on release they will only be able to sell ONE copy because of all the preorders they got, it may be that you are just in the minority.
Also I don't know why you are criticizing the whole "Year of the Luigi" thing. Especially when you stated that you fear that they are trying to bury Mario, when you yourself have made videos basically chastising them for putting Mario on the forefront of everything.
Also yes. Luigi has a lot more personality than Mario, and honestly that means he has a lot more freedom to be put in various games.
