@massivelyop i did: I did a mission for a #TSW plugin called Untold Stories: http://untoldworld.azurewebsites.net/ and I helped design and created Adventures (as Quest and Mission are reserved words) for a #LOTRO plugin called Your Own Adventures https://www.lotrointerface.com/downloads/fileinfo.php?id=1080

@massivelyop I wish I could recommend #TSW 😭 (it was the perfect second MMO, because it had such a great setting but mechanics not really suitable for complete newcomers to the genre - I know, many who were supposed to be seasoned gamers did not get them, but shame on them, not on the game)

@massivelyop It really depends on the setting. For "theme parks" (a la #LOTRO, #TSW or #GW2), I prefer hand-crafted design (I don't like the tentative procedural that some try to implement in their instanced content). For more sandboxy games (like Aloft), I like player-generated content - although that's what stops me for playing sandboxy games with a strong IP like Conan Exile or Dune...

@massivelyop Secret World Legends, because of disk space (it was this one or Classic #TSW). And Bullroarer was out of question, even though I go there less than once a year.
Bonus game: I didn't reinstall #GW2 when I upgraded my PC (disk space, once again: my new data disk is half the size of the former)

@massivelyop I said I'd go back to #SWL to finish the quest line when the bug that blocked me were fixed. Truth is, I changed my PC and didn't reinstall the game (it was this one or the original #TSW. Guess which one I chose 😇 ).
That said, I shift my playtime to other things in #Lotro just because a quest I'm running on my main is currently randomly bugged (and that random is constant for me. Hopefully it will get fixed or I'll be able to reset it successfully next Wednesday...)

@massivelyop as a system, the classless system of #TSW (what can I add to it?)
As a skill, the OG enrage in #Lotro, a burglar skill that made the mob attack randomly. It eventually got removed after it broke quite a few boss mechanics (most prominently Nornuan, who stacked DoTs on whoever had aggro, but the aggro rotation made it easy to absorb...)

@massivelyop #lotro's warden is a category on its own, requiring to master the gambits AND the lag compensation (not to mention the forecast of the ennemy's actions).
Or #TSW build-your-own-build (which isn't a class in the strict term but was what took place) was apparently found too complicated for the average MMO player...
