A thought: if I were starting today, I wouldn't be interested in D&D.
The reason for this is that as I've grown older (and become more set in my ways) my patience for newness for the sake of newness has shrunk, and my patience for gimmicks has become almost non-existent. It's not a resistance to change per se, but if you expect me to do something different then there have to be obvious benefits to doing it the new way - as I've said before, it needs to be "better enough" to justify the change. If you try to sell me on a new way to do essentially the same things as before about as well as before, you're on a hiding to nothing.
A particularly good example of this is music file formats. In principle, I wish we'd settled on a file format other than MP3 for music - in particular, a lossless format would be a better choice overall. However, the reality is that MP3 has effectively won that battle.
And so, if you now expect me to adopt a new music file format, especially one that requires that I install either a custom codec or, worse, an entire custom player, you're going to get significant resistance - the sad fact is that my hearing isn't good enough to actually notice a difference, so you're asking me to go through a bunch of hassle to get the same result. No thanks.
(Likewise, there's a debate regarding PDFs for the 5th edition books. WotC have now made electronic versions available through their "D&D Beyond" offering. Apparently, these electronic versions offer a whole bunch of features that PDF doesn't. Which is nice, I'm sure. But, as far as I'm concerned, they might as well not have bothered. Let me know when they get around to releasing PDFs.)
When it comes to RPGs, then, my tolerance for gimmicks is marginal. These are, fundamentally, very simple games. If you decided to tack on a whole load of additional bits, those bits need to offer a clear benefit... and, mostly, they don't. Adding cards, tokens, and such things just add new stuff to get lost. Or more stuff that I have to cart from place to place. Oh, and of course they add new ways for the company to charge money.
Which is fair enough - but where's the value-add?
Which brings us to the FFG "Star Wars" game (and their "Warhammer" third edition) and also the Goodman's "Dungeon Crawl Classics", neither of which I even considered adopting, for one simple reason: custom dice. In the case of FFG, the dice are marked with specialised symbols that have some sort of meaning within the game, and which therefore are of no use for any other game. DCC, on the other hand, makes use of the standard d4, d6, etc, but also adds a d3, d5, d7, and so on. Which is less annoying, since at least it just means I'd need the dice, rather than having to learn to interpret what they mean, but it was still enough for me to ignore the game until recently.
Of course, the argument against games that require specialist dice applies equally to another rather well-known RPG: D&D itself. After all, before I started playing I didn't have any polyhedral dice, and compared to 'regular' dice they're awkward and hard to get. (And also, the purist in my wants to note that dice with numbers on are an abomination. Pips all the way!) What's more, adopting those specialist dice mostly doesn't get you much - the difference between a d4, d6, and d8 probably isn't worth worrying about, and becomes effectively meaningless once you add modifiers to the rolls. (That said, adding the d12 and d20 does have some value. And the d% does also, though there's not really sufficient justification to have both a d10 and a d12, and also the d10 isn't a Platonic solid so should be rejected on those grounds. :) )
The upshot of all of this is that I've come to the conclusion that my rejection of games that require custom dice is largely due to a fairly arbitrary distinction based on "what I have already". Plus, it helped significantly that I was recently gifted a copy of the DCC quickstart rules, which are interesting enough to justify investing in some dice.
Oh, and it also leads to another conclusion: the best advertisement for an RPG is an evangelist.
(That said, I'm still opposed to FFG and all their works!)
