Yo n, great long post (I am not going to quote that), but that sounds great.
Keep everything we recognize as "Nintendo" familiar, and update it. Keep Mario Mario, and Zelda Zelda, but continue to update them as Nintendo sees fit. However, update the graphics (which the Wii U is doing), update the console memory, update the software, update the online... in fact, just update everything technological. Keep all the good ideas (Wiimotes and the Wii Motion Plus, Nunchucks, Virtual Console games, Wii Ware-esk games, motion gaming,) and add to them (with stuff like DLC, patches, and constant hardware upgrading via the internet). That and bring in new, young talent to continue Nintendo as a company moving in the right direction, to keep the great franchises running, maybe revive some old franchises, keep the modern franchises running, and maybe even make newer franchises (the only one I can recall Nintendo making on the Wii was the Wii/Mii series).
That sounds like a good plan to me.
I was personally very happy with Brawl's stages. Stages such as Mario Bros. and 75M gave the arcade roots of those series proper representation. Mario Circuit represented the Mario Kart series, while Smashville represented Animal Crossing. I really did like what was done with the stages, especially in the light of how they sometimes were used to represent an aspect to their respective series. I am personally hoping we see more of this in Smash 4.
I was happy with the choices of games with stages (Donkey Kong, Mario Bros, Super Mario Bros, Luigi's Mansion, the Wind Waker, Twilight Princess, Pokémon Diamond and Pearl, MOTHER 3, F-Zero, Metal Gear Solid, Sonic the Hedgehog, Metroid Prime, ) for the most part. However, most of those stages were amongst the crappiest in the franchise.
75M was awful (100M or 25M would be better), Mario Bros felt awkward, Mushroomy Kingdom went too fast and had too low of a ceiling, Luigi's Mansion was too big and too easy to camp in, the water in Pirate Ship made it too easy to survive (and it should have been more complex), the Bridge of Eldin was just poorly designed, Spear Pillar had a poor design, Pokémon Stadium 2 had dumb transformations, New Pork City was just an awful clunk of objects, Port Town Aero Dive had unpredictably fast F-Zero racers and the stage went by too quickly, Metal Gear Solid was way too easy to survive and camp in, Green Hill Zone had several glitches and just seemed to favor hit and runners too much, and Frigate Orpheon, while a great stage, had several glitches.
Overall the new stage choices were nice, but the way they were designed was poor. I hardly play 20% of them. Plus most stages have major glitches. Nearly every stage made the game feel too much out of the players' control. It might just be the physics and the game (Brawl), though. Those stages felt like playing Super Monkey Ball all over again!
It appears I am the only one that really loved the Mario Bros. stage. I guess it helps that I used to play the Mario Bros. minigame in Super Mario Bros. 3 all the time when I was really young.
I used to do that too, but I still hate the way the stage was designed. I think it could have been pulled over better. I'm not sure how, but I'm positive it could be done.
