Yeah, eh! And Micro Game$, plus plus....

...anyways, I don't have a GameBoy Colour so, after reading about Metroid II and such,
and the GBC games I've got..ta-da a thread...on community forums of nlife.

any thoughts on this/these (read title and post thoroughly) , now we've got it covered.

_{... i don't understand ...}

I think he means the gyro part of the 3DS could make Tilt n Tumble on VC possible.

I'm not sure that is true but I hope so as that game was great.

I think you mean Twisted! since Micro Game$ is already coming and doesnt use a gyro

I think the only other gyro game is Yoshi Topsy-Turvy/Universal Gravitation.
I found that rather awkward to play. I had to make rather exaggerated motions and a bit hard to follow since the only visual indicator of the gravity direction is Yoshi's sprite.

Staying ON TOPIC your idea there is interesting. I'd imagine any game from the GBC/GBA era with a motion sensor in it probably could be adapted to use the gyro. It wouldn't straight up work without a little recoding to read the new pathways to that part vs the original built into the cartridge, but I can't see any real reason why it shouldn't short of laziness, incompetence, or just lack of interest by Nintendo. Wario Ware, Yoshi, and Kirby would work out I imagine nicely this way.

when do you like motion controlling manoeuvres?
would you like it optional?
would you like it used only in certain times in a game when you want more elaborate moves, though don't need to when "normally" going through a game?

these may have already been asked, answered and such to varying degrees, however,
if you believe you have the time to take away from playing a game or reading, write a message here.
even if you don't understand, it's ok, too

Curiosity isn't optional,
however you could still complete a game,
bypassing the curious moments or time,
when you (accidentally) learn about a "super-cool-move" or motion that can be performed
to gain more points or other/extra parts of the story.

I haven't even played Kirby Tilt N Tumble by the way.

As cool as a Kirby Tilt 'n' Tumble port would be, I know I wouldn't be comfortable playing it on the 3DS. One of the features of that game was that to jump you would have to flick the GameBoy upward. That worked well enough on the GBC and GBA , but on a system like the 3DS where the main screen is attached with a hinge, it gets annoying having to reposition the screen every time it got loose from the "clicked" position. Try playing the game on the GBA SP, and (once you get used to the inverted tilt controls) you'll see what I mean.
