Holding a Wiimote horizontally (which mimics the NES controller) to play a modern 2010 Metroid game is terrible beyond words. You literally have to then hold it vertically and point it at the sensor bar in order to shoot missiles which stops you from moving. Also, the auto lock feature added to Other M allows you to point somewhere near the enemy and have your shots guarantee a hit. This means "skill" really isn't needed like it was in the prime games.
It is a poorly made, poorly executed and poorly received game. Because if this, Samus in SSB4 will be worse than low tier. She might be Other M tier!!!!!
I can see it now. The match starts and The announcer says "3, 2, 1.....Go" and BOOM MegaMan and his red doggy named Woof Woof come running at Samus shooting his little poop pellets while the dog barks obscenities. Samus, in her Other M mentality, yells to Adam "what do I do?" Adam respond, "you are authorized to.....to....run. Yes, run." While samus runs she questions AdaM with "Why can't I fight back, Adam?!?" Adam, taking his time, says "because.....you.....are...not wearing.....METROID PRIME 1/2/3 SUIT YOU STUPID EMO GIRL WITH A MAN VOICE!" Within minutes, samus is ripped to pieces by Woof Woof as MegaMan cuts off the Other M suit with his saw blade he stole from MetalMan's underwear drawer. The end.
That WILL happen in smash 4.
