Oh! Sorry for the double post, but:

After FFVII it would be Sonic 2 on the Master System. Crystal Egg Zone was a hoot!. I wish they did that zone on the Mega Drive, totally trippy.

the original batman for the nes. awesome game and gameplay that no batman game after it even has come close to it. took me days upon days to beat the joker till i read somewhere to just punch him and hell die. they need to bring back that typ eof batman game

Being the best in the world in Street Fighter Championship Edition (Arcade)

I don't know, it is a toss up between beating the Ultima Weapon in FFVII or collecting the 100 Gold Skulltulas in Zelda:Ocarina of Time both of which dragged on for days but the feeling of achievement when I completed both tasks was immense.
I think I need to get a life! :))

Beating Super Mario World (first game I beat). Recently -- catching 2 fish in Ordon village.

FFXI
soloing Charybdis as a 75NIN/37RDM after camping it for 8hrs, used a few regen drinks but it was damn hairy at times especially when it took out 3 shadows in one attack straight after Utsesemi: Ichi and my Ni isnt ready.
Maxed Evasion/Subtle blow FTW!

Too bad i quit before i tried to solo Genbu as NIN/RDM, was seriously gonna try it even tho i may had to have waste 500k gil for pop items.
