I did not know the "He" you were talking about until I Googled Space Harrier and the name Yu Suzuki appeared. I had seen Air Twister at Amazon in the budget section, but I would never have associated the game with Space Harrier. The reviews I have read for the game are not very flattering. I saw that Yu Suzuki's name is credited on the back cover art, so that's cool. I see the German publisher ININ on the cover art and they often partner with Strictly Limited Games who also sold a version of Air Twister. I actually prefer Strictly Limited's cover art for Air Twister and it sold for $29 also, but is sold out. The pictures of the games contents at Strictly Limited appear to show a multi page game manual was included. The retail version of Air Twister has a two page fold out manual showing the control scheme. I wish I could find out more about the Strictly Limited manual to see if it justifies paying a scalper price on eBay. Not that I'm into 3rd person forced scrolling rail shooters. But somehow I've managed to collect a bunch of them. In fact I just added Battle Ace for the SuperGrafx the other day. Because of the pedigree, I will definitely be adding Air Twister to my collection. But I will most likely wait until I can snag it for $$19.
Space Harrier wasn't a Simple 2000 game on the PS2. There was a 2003 Sega Ages 2500 Series Vol. 4: Space Harrier and a 2005 Sega Ages 2500 Series Vol. 20: Space Harrier Complete Collection released in Japan. But the last Space Harrier on a console was 2014 SEGA 3D Fukkoku Archives on the 3DS, also released in Japan.
I like sarcasm. Is this a joke?
