You asked what are the five versions. There was original Dungeons and Dragons way back in the day. So long ago that all the details from that era of the table top role play gaming hobby are obscured by first hand account folklore. Then a new age dawned, and it gave us Advanced Dungeons and Dragons, so we started over and counted all dungeons and dragons that came before as one, and Advanced Dungeons and Dragons as two. Then there was Dungeons and Dragons Second edition. And it was good, for a time. And Lo, the wizards smote upon the mountainside Dungeons and Dragons Third Edition! we're now up to four if you're counting. Five is Dungeons and Dragons version 3.5, and the d20 license juggernaut that launched a thousand genres under a horribly cancerous unwieldy splat book explosion. but this freedom given to the fan base went too far with the book of erotic fantasy... The powers that be identified many problems with 3.5 rules as written and made a list of things to correct going forward the money split into two groups. The first group stayed with Hasbro's empire and made the stupendously thoroughly playtested Dungeons and Dragons 4th edition. or as I like to call it the Hasbro Grid Based Combat Resolution Miniatures System. Sixth version of D&D. the second group joined Pazio and corrected all the same mistakes from 3.5 in their own way and made Pathfinder. about this time anyone with the money to publish a fully formed and polished D&D like game system... pretty much did. so you have a pretty big selection of games in the fantasy (Sword and Sorcery) genre to choose from. we'll lump that in together with pathfinder and call it version 7 and finally, there are officially successors of Dungeons and Dragons fourth edition coming out, Fifth edition (version 8) and D&D Next (version 9) Does that answer your question? I have a question for the boards, anyone care to put dates with all of those back versions of Dungeons and Dragons?
