Figures, its probably all pre-teens. If they would take the effort to look into the rankings they would know that win and losses do not count! So quitting just denies both of us the stats!
Not necessarily the age group, although that's part of it, but I think the way the gaming experience works has a major bearing as well.
The consoles' are very much about "instant on"; you stick in a game, even if it's a game you've never played before and you're straight in there, playing right away. I don't believe the addition of operating systems on consoles have slowed the experience up much, have they? (The last home console I have owned was an N64.)
With PC's on the other hand you immediately have a far lengthier boot up process to go through every time your start up your machine. Then, if you've got a new game then, you've got to go through another sizeable wait while you run the install sequence; this might even require downloading and installing a patch, new graphics drivers or so on. Only once all that is done can you get playing. Basically you've naturally got to have some degree of patience built into your gaming psyche because your gaming routine just isn't as instantaneous as on a console. I think that mindset means that PC gamers are more willing to be patient if things aren't going particularly well for them at a certain time in-game.
I also think that generally multiplayer opponents on the consoles can seem a lot more faceless or less human than on the PC. Online gaming is still in it's relative infancy and the consoles and the means of communicating between players are still being established (although, AC2009 with it's complete lack of chat capabilities on all platform, is an anomaly). I do say this as somebody yet to own any net enabled console beyond a Nintendo DS though and unlikely to in the future (I might be tempted by a WII if it fell into my lap). Anyway - I think having it established in your mind that this a person you're playing against and not just the product of endless lines of code is more likely to make you see things through if you have any degree of conscience due to natural empathy.
Anyhow - that's just my hypothesis.
anyhow, if it is not fixed in the patch, it will be height of incompetence on Codies part.
I wouldn't get your hopes up, nor would I personally see it as incompetence. They'd choose not to do it because of the extra investment required in what would be, in their opinion, a non-essential feature for a game that's already sold the majority of copies it's going to. I don't think that can be labelled incompetent as there's defiantly some logic there, but it would be short sighted. They'd be gambling that people don't come away from AC2009 so frustrated from quitting issues that they'd hesitate from buying the next game in the series. The same applies with any other bug or issue they decide to leave in.
If they don't to anything about it in the next version (AC2010/11) then that
will definitely be incompetent though.
