People are nostalgic for BECMI for a number of reasons, but primarily because it was what got them hooked on D&D. They may have played through the solo adventure in the Basic PHB and then run out and bought AD&D, or they may have played BECMI for 15 years and built a character all the way up to immortality. In either case, the design of the game as an introduction to the limitless fun of D&D is what captured them and made them remember those sets fondly.
I understand.
My point though is that Basic and all the subsequent sets were their own deal. There were modules published for them, etc.
What's now known as BECMI was a full on ruleset that people could stay with or could drop and move to AD&D if they wanted.
What has been offered since then is a gutted version of the rules, whose only purpose is to be an "introduction" so that people will spend money buying the "main" or "full" game. And _that_ is what I have zero interest in. Currently, I don't know that the "Pathfinder Basic" is actually going to be something other than a neutered ruleset.
There's also a fair degree of nostalgia about how "great" the BECMI set of rules are/were. I'm not landing on either side of that particular discussion here, I'm simply saying that people don't hold the starter set that's been done for 3.x with any kind of fondness.
If Pathfinder Basic is genuinely a simplified ruleset and is actually supported? Groovy. I'll definitely buy a set. But I don't have any evidence to suggest it being more than some random one-off product with the goal of having people buy regular Pathfinder.
And honestly? I'm not _expecting_ it's going to be anything other than a one-off attempt to shuffle people into the "full" game. I mean, I find it difficult to believe that Paizo would actually support 2 sets of rules; my opinion would improve quite a bit if they did, but I don't see it as a practical reality.
That being the case, I can fall back to "I can't really get worked up about this product". I've already got a Pathfinder book so I can introduce people if I want, and I personally have extreme doubts about the number of people that have zero ties to rpgs and would be inclined to pick up the Pathfinder box that wouldn't be already be inclined to simply buy the "full" Pathfinder game anyway.
In other words, I would be genuinely surprised if Paizo was going to "split" their customer-base by having 2 different sets of rules. Given that I don't think they are, it means the "basic" set really isn't geared towards anyone other than already existing fans or people that _would_ buy the game regardless of whether it was "basic" or the full version.
Nothing wrong with that, just not anything I see much point in getting excited over. Another Pathfinder product has been made... groovy if you want to buy something.
