GrotesqueBeauty said:If it was more challenging and the enemies and environments were more varied I'd probably agree. As far as graphical charm it stomps NSMB though. The animation was fantastic. As far as Mario-esque platformers on DS in general I'd actually give the nod to Super Princess Peach. It wasn't that taxing, but if you go for all the extras it's probably roughly on par with NSMB's difficulty, and it's extremely content rich.
I agree that GSDS is a bit easy, and has little variety in the environment and gameplay, although I think it's a very replayable game. It's just something you can pick up any day, and kill some time with it. The game always gave me a relaxed feeling. I think they made two mistakes with it: waaay to many autosave points (flowers) in all levels, sometimes few seconds to each other, and then the recycled original levels. They looked very well on the C64, but in this DS version they look infinitely inferior to the new, more complex levels. That's why people say the game doesn't hit its stride in the first 5 worlds. Actually most of those levels are from the original game.
As for SPP, I really enjoy the graphical style, and the vibe meter was actually a great addition, also the way you improve your powers during the game, however the game somewhat lose its appeal as soon as you figure out where and how to use your emotions. I also dislike the bossfight, it's kind unattractive. However I love the way they reuse some of the forgotten original enemies of various Mario games.
