Yeah, at least Old School Runescape gets weekly updates. It's apparently bigger than something like Elder Scrolls Online. Community is also really active, with an open-source client (https://runelite.net) and one of the best game wiki's I've ever seen (https://osrs.wiki).

Fun fact, JaGex at some point decided they wanted to ban the RuneLite client, riots ensued, and now RuneLite is actually listed on the official website.
