Jesus christ no. NSMB sells more because it's more accessible and has multiplayer.
And there are plenty of other accessible games with multi-player that don't sell nearly as well. Why do you think that is? Those games don't have Mario.
What I'm getting at is that Mario games sell well because they're Mario games, and Nintendo games don't sell based on their quality. Nintendo games sell based on their familiarity. Mario isn't heralded by the masses because it's innovative and fresh; it's heralded by the masses because it's Mario and it's generally very safe when it's successful.
Nintendo knows that the quality of its games doesn't mean squat. That's why Kirby's Epic Yarn was a Kirby game, rather than a new IP. That's why the next one has Yoshi in it. Most Nintendo fans are too blind to recognize the quality of a game without the inclusion of a recognizable character.
I thought we were both being pretty ridiculous. Games don't substitute that easy. Overlord might be similar from a gameplay perspective, but Pikmin gets a lot of acclaim for its gorgeous world design and art - something that Overlord completely shits over. It is more of a game made to mock Pikmin rather than to sell to the same audience. Exactly the same situation with Zelda - Darksiders has some atrocious design choices.
edit: darksiders is less offensive than overlord, for the record
I wasn't intending to be ridiculous by any stretch. Shadow Complex's game play is clearly derived from that of Metroid, although it also adds some really cool abilities that complement Metroid's style of encouraging sequence-breaking very well. Overlord is a more adult take on Pikmin. I didn't have a problem with the artwork. Honestly, some areas in those games look quite nice, and the character designs are chock-full of personality. As for Darksiders, it is to Zelda what Overlord is to Pikmin. It's an adult take on Zelda.
I realize that games don't substitute that easily. I love Shadow Complex, but I hate most Metroid games. (I hate the floaty jumps in most of the Metroid games.) Thing is, people need to be encouraged to go outside of their comfort zones and try new stuff. It's very possible that what they're waiting for is already out in some form.
I'm a huge Sega fan, and I'll admit to generally preferring Sega's style of game play. That has little to do with recognizable characters and names, though. In most cases, I only like a single installment in any given Sega series. I could never get into the Shining Force games, either, but I love me some Fire Emblem. Sometimes, it's good to go out of your comfort zone and try something unfamiliar.
