Achievements or not, it's still a [darn] good game and still deserves recognition for being the better of the Mario games on the Nes, AND introducing a Plethora of gameplay additions and mechanics that are still in use today...which, yeah, were mentioned previously. Sure, it's not the GREATEST of all time...but to deny it's place in gaming history and in the hearts of those who grew up on the game all those years ago is just, to me, ridiculous.
It's still a really fun, really polished title that's amusing and bewitching players even today...it's a hard one to beat for the select few consoles back then.
