In ten years Wavemaster has released complete albums / anniversary boxes for the following Sega series:
2005:
Space Harrier
2007:
OutRun
Monster World
Hang-On
After Burner
Galaxy Force & Thunder Blade
2008:
Golden Axe
Phantasy Star
Fantasy Zone
Vermillion & Rent a Hero
2009:
Shinobi
Alex Kidd
2012:
Bare Knuckle
Not to mention many, many other releases (Sorcerian MD, the "Last Action Heroes" box, this one etc.) that pretty much have covered the entirety or Sega's arcade and consumer music history.
Dare I say, the most glaring omission thus far is the Shining Force original series?
