Lost Vikings is a pretty long game, with 37 levels (43 in the Sega Genesis version), and the sequel adds another whooping 31.
The sequel was released for SNES, PC, Saturn and Playstation. The original SNES version retained the same cartoonish graphics of the first game, while all the other version had completely redrawn graphics, in a style that I can only describe as “weird”. I didn’t like it all. They added full digital voice-over, but it wasn’t very well done either.
To date I prefer to play the SNES version, via an emulator. But you have to be careful – if you get the PAL ROM, it will run slower than it is supposed to, and some of the dialogue will be missing.
