NSMB, NSMB Wii, NSMB 3DS, and NSMB WiiU all look exactly the same and other than the different suits, feature nothing - no gameplay mechanics, no tone, nothing - that sets them apart from one another. The only retarded thing is that they're alike to a fault.
EDIT: I'm retarded. Thanks, Reclaimer. >_<
Just would like to point one thing out.
Where does the "every NSMB is exactly the same" come from in terms of gameplay?
There's only two NSMB on the shelves. We have not played NSMB 3DS or this Wii U game.
Comparing NSMB to NSMB Wii, the Wii game has:
New power ups.
Yoshi.
Multiplayer.
Koopa Kids sub boss system.
Level concepts that didn't appear in NSMB.
Tons of gadgets, toys, and enemies that didn't appear in NSMB on the DS.
It's the exact same game as the DS title... how? Everything listed is about the same amount of new stuff added between say, SMB3 and SMW.
Yet every time NSMB comes up, a lot of people chime in to say "lol they were the exact same game in every way, oh I think the Wii port had a propeller suit. Still same game."
People are now concluding as fact that the 3DS sequel, and the Wii U game, will be exactly the same with no new ideas whatsoever based on a couple of screenshots in the case of each game.
Why does NSMB bring out this kind of reasoning?
I'm sorry it's just... it creates the impression that pure irrational fannishness is causing people to make things up to justify why they don't like the way the foreground blocks look in the NSMB series.
You could go back and construct the same argument about every 16-bit Sonic the Hedgehog game, because between all four games (the fourth of which was literally an expansion pack), the 'art style' only changed slightly, there were only a couple of new power ups, and the only difference was the level construction and interactive gadgets changed.
The only legitimate criticism in this dimension one can make against the NSMB branded games, is that the Wii game didn't introduce any wholly new world themes among its 8 worlds. It was more of a dramatic expansion of the original DS game's concept.
If NSMB 2 doesn't have a single new world, yep, that will be an authentic demerit. The Wii U game, based on the very first image scene, is expanding the environmental theme. But we will have to see what it does across the entire game.
