I thought I'd post some stuff pertaining to one overlooked character. First off, the Super NES game:
From the same people behind the equally underrated Skyblazer; this game mixed platforming and fighting together. I personally thought that this wasn't bad by any means, but could have used some tweaks in its favor. The music and graphics are great for a Super NES game.
Spawn: Armageddon for PS2, GC, and X-Box
Spawn: In the Demon's Hand (Arcade and Dreamcast)
And here's the short-lived animated series...
Not the best animation, but the writing and voice acting compensate for it.
Regarding the subject being used as NG fodder: I think more people should consider using McFarlane's series as spoof material in the vein of Gotham Heat and any parody by Wogoat.
