Got a bit of a rant to say, but its not directed at you. Basically it involves another board where they were complaining about "loser series in the game" after the latest scan with Ta-chan and Makibao. The truth is that both of these series do have their fans and their moments in the sun in Japan, where Jump originated. Just because they aren't in Jump at a period where you could download the whole magazine by various means doesn't detract from what they are and the appeal that got them in to JUS. In fact, the whole matter regarding these two series made me wonder: if the internet (which we all know has shrunk the ocean drastically in the means of manga distribution) had existed in a former period, when there was still a Shonen Jump but before now, what would people be obsessing over or reading? What would they have been scanslating? And how would they react when some new series start with no guarantee that they will last to the point they are at now?
The first date I thought up in this study was 1988, particularly because of an old Jump magazine I found one time from that particular year. In particular, it was the very issue with the first chapter of "Rokudenashi Blues", which has been confirmed for the game. If the internet and scanslations and such was around in '88, what would we have been reading? Obviously "Dragonball" is the obvious first choice: the chapter in that issue was during the 23rd Budokai, I think specifically the point where Shin (Kami in disguise) wins his first major match. "Saint Seiya" and "City Hunter" were in its glory era too, while "Fist of the North Star" was in its final stages. (it ended in '88 according to Wiki) Wouldn't be surprised if "Sakigake!! Otokojuku" was being done then too, but I personally don't know how big it would have been. Then there's "JoJo's Bizarre Adventure": at that moment they were in the middle of the Joseph Joestar story (part 2), before the series became more notable with the introduction of the Stands. I can't remember if "Ta-chan" had started by then, but if it did…well, since "Jaguar" hasn't really been done, it may not have been either. (gag manga have a harder time getting support at first...look at how long Bo-bobo waited for scanslations) Then there's Kochi Kame...but that I'm less sure of since it already had 12 years. Other than that and what I know, those probably would have been what we would look at and respect.
The next date I thought about after that was a more recent but slightly far off date: 1996. The web was a much smaller world back then, particularly in the manga distribution we know of now. (Ranma was being translated but that had a foothold in the US) But if it was much larger...some translators and fans would probably still be in mourning the ends of both "Dragonball" and "Slam Dunk", but this was the glory era for "Rurouni Kenshin" and there might have been a "Hell Teacher Nube" translator with the anime that year. (if there wasn't one already) Heck, I could have seen fans translating "Midori no Makibaou" and "Sexy Commando: Sugoi Yo, Masaru-kun!" The only really notable new series that I don't know would get anyone at first was something about a kid being posessed by an Egyptian game king...then again, if reading the first chapter would lead you to the direction of it being the source of an overblown card game and a dub from 4Kids. Oh, and I don't know if anyone would want to translate the one-shot about the rubber pirate yet. ;p
OK, maybe I did get off track, but I guess the point is clear: just because there was no web to follow these series like there is now with all these Naruto and Bleach followers (OP too, but trying not to create battles) doesn't mean all the other series are worthless.
