Gearheads of War

No, they came out in the u.s. There were like 5 games, and only one of them that you should go out of your way to find. There were 2 gameboy games, one was a bomberman game that they renamed to try and cash off on what little noteriety Blaster Master had. One  was a gbc game which was pretty much just a remixed version of the nes version, but it moved slower so it never felt right. There were proper sequels on the genesis and ps1 but they never got the phsyics right, the tank didn't have that purposly sluggish feel it had in blaster master that made you feel like you were driving a tank. They didn't have the topdown portion, which was awesome cause it made it feel like it was 2 games in one, and the soundtracks were really dissapointing.
The game you should look out for is Fester's Quest, not a blaster master game, but it used a retooled top down portion from the first one.
Some games get really impressive sequels, Blaster Master unfortinly wasn't one of them.
