Awesome game for sure.
Personally I like Fusion just a tad better, but that doesn't really take away anything from this game. I have played it on the SNES back in the day, but it was briefly and I barely remember. I don't have the SNES game myself, so it was probably at my aunt's house. It wasn't until the 30 cents re-release on the WiiU when I truly got into this game. Needless to say, I couldn't stop playing. That sounds like a good thing, but the consequence is that you're done with it way too quickly .
Definitely wouldn't mind an original 3DS Metroid based on this game .
