lol. i got bravely default as well (actually i pretty much have every 3ds game thats worth owning), and thats one i havent touched at all yet. paper mario was the only game i ended up playing out of the games you listed. bravely default feels like it would have to be a huge investment. one i havent been willing to make yet. TTYD is a massive game. that one should take awhile. if you plan on 100%ing anyway.

Nope, will eventually get Kirby Triple Deluxe for my 2D Platformer fix!

I've played a fair amount of it with my nephew (I bought it for him; he's four)...
It's not bad at all...
I actually like it more than the original (I find the first one horrendously tedious)...
I never played Yoshi's Island DS...

I have been playing Yoshis New Island the past few days myself, borrowed my brothers game, he bought it. It's definitely better than the ratings it has got. The graphics look horrible in still images but in motion it's beautiful. There's more than three songs too, at least 6-7 plus remixed versions. By remixed I mean very different. The main tune which is in many of the songs is good too, composed very nicely. Good use of 3D.

It's not all good though, the controls feel much heavier than the old ones for example. But overall it's a good game which deserves better scores in my opinion. It's also harder than I thought.

On world 4 so far.

It's made by the same group behind the Yoshi's Island DS game which was a travesty of a game, so no thanks.

Maybe when it drops to around $25ish

I thought it had lack luster level design, and the soundtrack was awful. But, it still disagree with it's metacritic score; I'd personally give it a 7 or 7.5.

i can see how somebody wouldn't take to the music initially, but after playing through the entire game, how could you not appreciate what they have done with it? the weird squeaking that occurs did throw me off and i thought it was stupid at first, but it grew to be very very endearing to me. i love the squeaking now; it gives the game character. i like how they incorporated the squeaking in world 3-5 for example. its hilarious. and then the spin that world six takes on the music i think is awesome. didnt you like the world six music? i thought it was very fitting for the end of the game. 

the boss fights, i am assuming that you think they are too easy, and they really are. way too easy, but i have to say that they are creative. i will not take that away from them. also, the difficulty is a bit higher if you consider the fact that you cant get hit when you face them. so i can see it both ways with the boss fights.

the first one was a masterpiece. did you play it in 1995? there is nothing wrong with that game. 

yoshi's island for DS is basically just like the original, only ten times harder. literally.

world 4? wait until you get to 6, i really feel like it ties the entire experience together. that may sound dramatic, but i really felt like everything you have done in the game before that point has prepared you to take on that world. the game does a nice job challenging you in various ways throughout the game to prepare you for the onslaught that it world six and its secret level (i am of course speaking from the context of collecting everything in the levels).

also, i do recommend using the gyroscope. it makes the gameplay more, for lack of a better word, intense. i know people hate when motion gets involved with gaming, so if youre one of those, then youre more than likely not going to take to it. but if youre open minded with it, i think it could enhance the experience for you.
