What is/are your greatest game achievment ?

My greatest achievment would be beating Shining Force 2 with Bowie, Sarah and Slade only in the hardest mode.
I might do it again one day with Sarah or Slade only.

Im probably gonna try to get excalibur II in ff9 at level 1 then beat Ozma at level 1.

Edit:

I used to beat Punch out on nes my eyes closed.
