If you want Nintendo to make harder games, you have 2 paths that involve going to Japan to follow. Choose one
1: Buy plane tickets to Japan, find the Nintendo of Japan HQ, sneak into the building through the air duct, find Shigeru Miyamoto, drop in through his office, and ask him to make harder games.
2: Follow all the steps, except instead of going through air vents, bribe the guard.
Either way... You still have to have a translator.
Another thing; now (most) game developers are focused on making their games pretty and forgetting about everything else, such as plot (translator for Miyamoto, are you reading?). If you still think this is untrue, play Mortal Kombat Advance.
Also, if Mario Advance 2 is too easy, did you play (and beat) the SNES version? If so, I've one thing to say: No crap it was so easy!
You might be a Mario Maniac if...
1: You have built a small shrine to the N64 you bought on launch date.
