I first began gaming seriously with D&D and AD&D back around 1985 or so. I was an early adopter of AD&D 2nd Edition and the original World of Darkness. I ran an ongoing D&D campaign world from 1992 to 2011 (passing from 2nd edition to 3rd edition to 3.5 edition), when I left the state of Rhode Island and Providence Plantations where that game was based, and moved to Arizona.
I am happy to say that I have started another campaign that I hope will be just as long-running as the one back in RI – the Pathfinder campaign “Heroes of Midhgardhur!” Why Pathfinder? Well, I loved D&D3.5, and I am saddened that it is no longer supported. I looked at 4th edition “D&D,” and I was horrified – it is an abomination, not even D&D in any sense that I understand the game. Pathfinder keeps the best of 3.5 alive – in fact, it fixes a lot of flaws from earlier D&D games.
At some point I might be talked into reviving my New World of Darkness chronicle, “The Whitethorn Foundation,” but that is really a project for another time. I am also absolutely enchanted by the new Dungeon Crawl Classics RPG, and I would love to try it out sometime. DCC and the original conception for “Midhgardhur” share a lot of the same roots in Appendix N.
Post Scriptum: New developments in the world of D&D have not really changed any of the above opinions. D&D 3.5 is no longer supported, regardless of recent reprints of the core rulesbooks for 3.5 (and 2nd edition, and 1st edition!). D&D Next (D&D 5th edition) looks . . . interesting . . . but I have really fallen in love with Pathfinder and committed to that as the fantasy RPG system of choice for my campaign (although the Dungeon Crawl Classics RPG looks awesome and I must try it at some point!).
