Possibly the best Metroid game ever made, Super Metroid is also my personal favorite of the Metroid games. I haven't beaten it yet, but it's really fun. I got to this one part where i was like "WTH?". I'll post a pic. Also I posted a picture of Samus dieing. Epic death.
(Btw I DO use emulation software to play Super Metroid. Don't say "OMG emulatino you gonna get banz!!11!one" because in the rules it says emulation is perfectly fine to post about.)
