Best SNES game? I think you forgot a couple contenders:
Super Metroid and Link to the Past are still considered by many to be the best games in their respective series and are certainly worthy of mention here.
Then there's RPG's like FF6 and Chrono Trigger, which are still my favorite RPG's ever.
Mega Man X is great, and Super Mario World was awesome... but if we're talking the absolute best SNES had to offer they definitely have lots of competition.
Oh, absolutely. It wasn't my intention to make it sound like these were the only two viable games to be considered the best on the system.
I'd even go as far as to say the SNES has the best game library of any console, ever.
Agree/disagree?
That's a really tough call... Definitely the best of the 16 bit era and through the PS1 era. Lots of goodness in the newer generations though.
This could be a good idea for a blog post or a few even...
