But it's only recognition from people that know what D&D is and how PF relates to it.
I'm sure that if the brand were ever for sale and the price made sense to Paizo, it'd be a no-brainer for them.
This is increasingly becoming less true as Pathfinder grows. I'm not saying a Pathfinder brand is going to equal a D&D brand any time soon, but it can happen. It'll probably take years (if it happens), but it's far from impossible.
I introduced my kids to RPGs via Pathfinder a year or so ago. When we play, we're playing Pathfinder, not D&D. I'm now gearing up for my 3rd PF kids campaign as my eldest has brought in friends. They only know Pathfinder as well.
=========
I'm also confused by the recurring wishing/what-if-ing for the scenario where Paizo could acquire the D&D brand and fuse the brand with a PF2.0.
1. If you're a 4e fan, presumably you're happy with the game and have no reason to want it to change ownership. WotC is giving you the game you want.
2. If you're a PF fan, why do you care if the game is called Pathfinder or D&D? Isn't it the game that matters? Aren't the mechanics and the play style they support why your preference is for Pathfinder and not 4e?
3. The Pathfinder RPG is still in its childhood. It came out it when, 2009?!?! Are RPGers that addicted to the "new shiny"? 4e isn't much older and rampant Internet speculation aside, I don't think 5e is right around the corner.
I fervently hope Paizo's success continues like gangbusters and does so without the D&D brand. Make mine Pathfinder!
