do you really want me to answer these questions, or are you placing numbers out of context and facetiously looking for a single answer that would satisfy them all?
I'm always genuinely interested in hearing your points. But I don't know that the PS2 had historically bad tie ratio through it's life, or even in early life. I believe you have access to more data than I, so I'm fine with being shown though. It reached about 6 games per system, after about 20 months, from what I can find. It didn't track particularly poorly against it's contemporaries. The 360 did happen to have a particularly good tie ratio from memory, but even then took about the same amount of time to reach 6 games per system I believe. It's also harder to maintain or increase a tie ratio when the base is expanding faster, for obvious reasons.
So I'm just not in favor of the idea that the system's driver was it's ability to play DVDs, rather than the ability to play games, with the bonus of being a DVD player.
then there must be some confusion, because i'm really only talking about the early part of the ps2's life where the dvd was a novelty and the ps2 was valuable because of it, and not its software library.
I thought we were discussing the validity or not of removing data for the purposes of analysis and whether it created a more or less meaningful picture. I think DVD was a selling point throughout the life of the system. But I also think that gaming software was the primary point of purchase for the majority of its sales, and for much of its 6th gen life-cycle the software that defined the system didn't particularly deviate from the traditional market.
And in saying that I also think the primary point of purchase for the Wii was gaming software, so I hope the above isn't misinterpreted. But it was selling quite different software, by and large, to a quite different audience.
i think the playstation 2 gamers spread out far and wide after the ps3's introduction. the ones really attracted to sony's software bought a ps3. the madden fanbase seemingly translated really well to the 360. the rpg fanbase essentially vanished from consoles and reappeared again on the ds and psp (especially in japan), and currently seems to reside on the 3ds. people who bought it for their kids when it was inexpensive probably got a wii afterwards. unlike some people (not you), i don't think userbases vanish into thin air- the thought is preposterous to me. the only way fanbases completely die off is if no one is appealing to their sensibilities anymore.
I don't know. I don't really look at it as "the JRPG fanbase" but rather the consumers those games were aimed at more generally, which I don't really think deviated hugely from a young male target audience. They were certainly more targeted towards the Japanese market than modern output no doubt, and the significance of different geographies has definitely changed. One could argue they were more accessible to female gamers, I suppose, (without hopefully getting into an argument about gender norms).
I also think it's entirely possible for consumer tastes to change, regardless of if one keeps outputting the same thing, as the individuals who comprise the market segment shift. They grow up in different environments, economies, etc. The 16 year old in 1990 eagerly awaiting the next Super Mario, is 40 now. The 16 year old boy in 2000 eagerly awaiting the next Final Fantasy, is 30 now. The 16 year old now is eagerly awaiting the next Call of Duty. In 20 years time that 16 year old may want something entirely different, on the assumption we have consoles at all. That isn't to say that fanbases necessarily vanish, but I think they can diminish, or move as you note, and that movement can be due to circumstances outside of control (for instance you note the shift to handhelds in Japan).
As aforementioned, I think the primary market of the PS2 was playing different games/franchises/genres, but I don't think the people (demographically) that comprised that market is hugely different to that which drove the PS3 and 360 and that which is driving the XBO/PS4 now and going forward. I think there was certainly a market segment within the PS2's installed base particularly conducive to the types of games the Wii brought, with things like DDR and SingStar, and whether that's still present is a question. But I don't think that was the primary driver of it's success and it came later in the cycle, so it's far too early to me to determine whether they return. I could certainly be wrong.
