Well that's the most polite comparison I've ever seen of an idea to soviet communism

. It's still utterly ridiculous.
It
was meant to be funny. But it contains kernel of truth...
Editions are like operating systems.
I like analogies, and I develop business software systems for a living, but this analogy doesn't really work. Put simply:
Gaming is easy (not really resource intensive) and done for recreation.
Software development is hard (very resource intensive), and (usually) done to turn a profit.
Therefore, the gaming community can support more editions/systems than the wider world can supports operating systems. The differences in resource costs makes this analogy silly -- at least in the way you seem to be using it.
For such a small hobby we have a lot of operating systems.
Yes.
Very rarely are their programs compatible with other operating systems.
Converting gaming materials is a tad easier than converting/developing multiplatform code.
We're talking about the potential size of the community rather than the current community.
If you're interested in growing the community, you might want to pay closer attention to what the current player base enjoys now.
Learning a game, any game, takes commitment.
Playing in a campaign on a regular basis take a significant time commitment.
Learning a game? No.
The thing this insulated forum seems to fail to grasp is that the barrier in terms of time and money to playing in and especially running role playing games is remarkably high.
Money is a non-issue. RPGs are cheap (purchasing most core rules costs as much as a single video game or dinner at a nice restaurant w/wine). Wait, let me amend that... RPGs are expensive if you're a completist (so don't be if you're concerned about costs). Also, 3e and Pathfinder are essentially
free. Time is a serious barrier to entry... but it's not like a new, evergreen edition of D&D is going to change that.
The point of entry product, a 300-page rulebook, becomes obsolete every five years or so.
My AD&D books aren't obsolete after 26 years. I'm using them to run a campaign as we speak (err, type).
A 40 year old who played AD&D would rightfully be terrified to pick up where they left off and start DMing with a 30 year old friend and a 20 year old nephew based on their different points of entry into the hobby and available resources.
A 40 year old who's terrified of that needs a Xanax and good therapist.
You couldn't rewrite an operating system like Windows and discontinue support for all existing Windows products and not expect an uproar.
Is Windows 95 still supported? Will a iPhone 3 run iOS 5? Wait, this is still a bad analogy...
I'm not sure how you invented that.
Admittedly, I was speculating.
