I played Dead or Alive 2 without playing 1 and Dead or Alive 4 without playing 3.
I played TES 4:Oblivion before the first 3.
I played Advance Wars 2: Black Hole Rising before the first.
I played GTA 3 before the first two.
I played Super Metroid before Metroid and Metroid 2.
I played Metroid Prime 3 before 2 but 1 first.
I'm sure there are more but I can't think of them at the moment.
Pixel Art can be fun.
