I'm referring to how the game has been played (at least in the groups I've been around) since 3E came out. I'm also basing my comment on how often "campaign" comes up on these boards. YMMV.
It does indeed. I see little or no change in emphasis online and in actual games on the same old overemphasis on rules (i.e. why the status quo rules are or aren't good, look how I've fixed it, no your house rules suck), metagaming (e.g. old chestnuts like paladin alignment issues) and campaign setting/worldbuilding (e.g. what setting should I use, homebrew pimping)....
...and extreme underemphasis (given their importance to the game) on adventure design and story arcs...it's much more fun to design grand macro detail like rules and empires and archdevils, whereas generating actual adventures seems too much like hard work to DMs and designers alike...apparently at least one WotC designer thought themselves above doing "a tower of orcs", they're
game designers...which means to them rules tinkerers...nevermind that
the rules aren't the game actually played, the adventures are, oh the rich irony and arrogance, especially when said adventures turn out to be average-to-poor in quality, no match at all for the
Baldurs Gates of the world...
...and this emphasis on what is arguably ephemera such as god stats and irrelevant worldbuilding (e.g. reams of history which would suit a novel but never enter the game and tends to bore players) as the place D&D gamers love to spend most of their time thinking, writing, discusssing, cussing and daydreaming about the has been the case in D&D as far back as the earlier
Dragon magazine forums. And it's still the case on these boards - metagame, rules, setting, gods/deities/archdevils ephemera everywhere, with occasional exceptions which tend to make their way into the best threads lists.
Back in the 80s and earlier, the campaign has been what D&D gamers aspire to and discuss the most. If there's been a change, other than the now extreme obsession with crunch and rules wrangling as a reaction to 2E's apparent failings, wowee, it's been subtle enough for me to miss...
