So lets look at the situation currently, not only has WotC given the golden goose (its rules through OGL) to Paizo and established its own worst enemy (strictly business speaking) but its now left the marketplace virtually vacant leaving current D&D players (wishing to stick with the familiar) with two choices: OSR or Pathfinder. Based on retailer shows and distributors I speak with, in the current retail market, there is only one true choice: Pathfinder.
That is not to say the landscape can't change, or that the vacancy in the market could not lead to an OSR game breaking out, but none of the current crop, good as they are, have achieved a sizable retail presence. So for 18 months there is really only ONE major D&D system based RPG game on the market, Pathfinder.
The next 18 months of Paizo's business will be extremely interesting, because I wonder if they see the same thing I do: an unprecedented window of opportunity. They beat WotC with their own game system and WotC left the market. It really is unprecedented.
To get a sense of what I a talking about: Imagine if Apple gave Microsoft the right to build iOS tablets and devices, MS produced better even more user friendly devices...and then Apple left the market for 18 months with a promise of iPad and iPhone next?? What do you think their stock and investors would do? Sure brand loyalist would stick by them and buy their release...but the world will have moved on.
Or if Microsoft gave Xbox live and Xbox 360 tech to Sony and Nintendo, and each built a better game system and online experience than MS...and MS said no problem we will be back in 18 months? It is, from a business perspective, unprecedented.
Would Wizards give all of Magic to Konami let them make the exact same game with different art...and then say okay but wait 18 months, then see what we do! no...freaking...way.
So I am looking at the next 18 months with much interest from a strictly business related perspective. I skipped 4th, and plan on skipping 5th or Next or whatever it is called, and I don't play Pathfinder so I don't have a dog in the fight really. I am just curious to see if, after building your own competitor, getting beat by him, leaving the field of battle for awhile, and then attempting a comeback, if it will work? Or will your competitor have gained such a lead that the battle is well and truly lost. Or will a young usurper, and currently unknown step in and take the glory? Time will tell, and what an interesting time it will be.
