The arcade version of Thunder Blade has been announced as the next Sega 3D Classic release.
While not quite as awful in its Genesis form as Galaxy Force II was, similarly to Galaxy Force II, gamer's that just remember the rough 16 bit conversion are in for a treat with this one since it was excellent (Sega really should've based the Genesis game on the top down portions rather than attempting the 3D sprite scaling bits).
Hopefully Sega actually releases wave 2 of their 3D Classics series here. They've been nice games all around so far with this round and no bland Genesis ports like Altered Beast have cluttered it up. It has been 100% arcade focused so far (Both Fantasy Zone's, Afterburner II, Outrun, and now this) with hopefully more surprises to come like Turbo Outrun later this year.
But rumblings are that Sega won't bring this group West like they did the first wave of releases late last year.
