Rare deluxe special edition for Enemy Zero (1997, Sega Saturn). Only 20 were made, and were sold for 200,000 yen. Kenji Eno, the founder and lead designer of WARP Games literally delivered these crates to people personally via a flatbed truck. Proof that:
1) Absurd and excessive special editions are far from a recent thing and
2) When Kenji Eno did something, he did it big. The man was dedicated and crazy, and I respect that.
