Another touchy point is licensing since the comic characters are brand names (and Sierra Entertainment probably exists in some fashion). They might only be able to release a demo.. which means modifying the game making it a "demo" version.
Activision owns anything that would be Sierra. I presume the BC characters are the property of Johnny Hart's family.
As a youngun, the wrestling game I played the most at home was Tag Team Wrestling on Commodore 64. In the arcades it went between WWF Superstars then moved onto Wrestlefest. After that I think there was nothing for me until Power Move Pro Wrestling for the Playstation which I loved to death.
This Sky Skipper mention is funny since I'm currently reading The Sega Arcade Revolution by Ken Horowitz about Frogger and it says that Parker Brothers was in the bidding for Donkey Kong before Coleco got the rights. Now, Sky Skipper did come out before DK in the arcades tho honestly, not sure if so for the 2600 but presuming so they may have thought they had an in with Nintendo seeing how they licensed with them previously. No idea what their bid was but obviously not enough to beat out Coleco who had the bulk sum plus royalties on Colecovision. Imagine how the console landscape would have been different if Parker Brothers were the ones to put out Donkey Kong.
Side note since I mentioned Frogger. PB had bid $250,000 then found out they lost the bid (not mentioned who won it at first) but upped it to $500,000 and got the rights. Parker Brothers doesn't get enough credit for the Atari 2600 games they put out. Insanely great catalog.
Honestly, the Sega Arcade book has been a great read so far & has info that surprised me since I thought I knew tons of things about Sega. I was proven wrong.
I was 10 years old when I first saw Space Invaders. It wasn't the first arcade cabinet I ever saw as I recall playing Stunt Cycle at a roller skating rink before that. I was walking to the local shopping center for my mother to get something at the supermarket. I walked by the bar in said center (this was late afternoon) and saw it in the window with that crazy side art. I walked in & and asked if I could play and the bartender 'Get out, kid. You can't be in here.' I said 'C'mon, one game'. He acquiesced and I got in a good 7 or 8 minutes on that quarter. I said thanks, went to the market and went home. Next day, told all the classmates what I saw & played. Fast forward 40 years, here we is.
Sky Skipper was pre-Popeye & Donkey Kong so after the failure of Radarscope Nintendo probably got cold feet releasing it in the USA. Much like Radarscope cabinets became Donkey Kong's, Sky Skipper cabinets that could have made it to the USA became Popeye's. Parker Bros, to me, was like Coleco, licensing quirky arcade titles that Atari and possibly Coleco to an extent, didn't want or didn't think would be big sellers. It sounds weird about Coleco with them at the start snagging licenses like Lady Bug, Looping ( a personal favorite) and Space Fury but hey, either way we got them. Parker Bros. had a very successful run of great games over multiple systems. It's kinda sad they don't get much credit these days.
