Star Blazers MMORPG?
No, no one's releasing this, but it was a nice daydream. I think a hypothetical game like this would definitely sell with the fans.
For those that don't know, MMORPG means Massive Multiplayer Online Role Playing Game.
Like Everquest, Star Wars Galaxies, World of Warcraft.
Set it in the time of season 2 so you can have more than one battleship. The Argo/Yamato would likely be unavailable. But you could fly around in an Andromeda class ship.
I know they'de never do one based on Star Blazers/Space Cruiser Yamato, though.
Looks like Star Trek Online (if it ever comes out) will be the closest thing to it.
