On topic: There are MMO RP communities in most games but they range from ‘Smaller than WoW’ to ’ Ridiculously niche to the point of being near impossible to find’.
If you know where to look though, you can find it.
And on the matter of housing, counterpoint: Wildstar RP thrived thanks to housing. But by design it was far more open, and addons were made to further facilitate that openness. By making it very easy to see which public housing plots were active, when events were being held where, and so on and so forth. Literally open a menu and you could see what plots had activity, what their theme was, who ran them, and if any upcoming events were approaching.
Sure in most MMOs like SWTOR or GW2, where housing plots are rather tiny and confined to a very specific purpose, Wildstar housing was the world in a sense. I’ll acknowledge it required some initial checking of the RP forums to see how it worked, but once I was pointed the right way I had zero issues finding plentiful RP.
People were able to make space stations, malls, jungles, spaceports, hoverboard parks and way more besides. Without that it would’ve been limited to the ‘actual’ game world alone, which frankly could not have easily replicated half the RP hotspots I remember engaging in.
I remember even making a hub myself as an apartment block with shops and a park that a bunch of people used even while I was offline, just because I set it to public and contributed to the RP plot addon listing. It was incredible.
Even without housing though plenty of events were still held in the world, but housing was great to let people create very specific environments and ‘minizones’ for events both public and private. I honestly don’t think RP would have persisted until the day the game died if it were not for the housing system in that game. I legitimately RP’d more than I might’ve done because I loved seeing what other people had put together, and some brainiacs even figured out some insane API scripting to make stuff work in their instances like rollarcoasters and fighting pits (Albeit jankily, but it worked!).
However, if the housing is very narrow, specific and very ‘closed off’ ala GW2 guild halls or SWTOR Strongholds, then yeah, that’s a problem. They end up serving as purely private instances and there’s little chance to find and understand which are active and their purpose can’t be used for much more than social RP. That’s not something I’d really want, we kinda have it already with Garrisons.
Housing where it’s just “Here’s an instance, and you can out furniture down” bore me to tears. Wildstar and Star Wars Galaxies nailed it and it saddens me that most MMOs go for the bare minimum instead of the awesome stuff we’ve seen elsewhere.
