I doubt this fits the exact purpose of this subforum, but eh. Just found myself thinking back to some little instances of MMO RP I’ve run into over the years and thought I’d share.
This wasn’t even in TSW/SWL but in LoTRO, my MMO of choice around 2011/2012. My character was Gondorian, and I had started a guild to gather RPers keen on playing Gondorians in exile (this was years before Gondor was added as a zone ingame). One day I got a message from one of my recruits through the ingame mail. Written ICly, it informed me, his commander, that he was returning to Minas Tirith on urgent business and would not be back for some time. He even spelled out the exact overland route he would take south to Gondor, and ended with an OOC postscript explaining that he was going on holiday in Europe for a few weeks. I remember how I smiled at that — it remains the single best explanation for a leave of absence I’ve ever witnessed in MMO RP.
Another time, my Gondorian met an Elf scholar who was studying the Dunedain ruins near Bree, and the two became friends over shared interest in Dunedain history and lore. Shortly after, this Elf began sending me ingame mails with Fragments of Dunedain Script (a farmable crafting resource) attached, along with transcripts of what she had discovered from said fragments. Too dense then to recognize an RP hook when I saw one, I contented myself with sending back similar items of an Elvish nature, and her mails eventually stopped. But I’ll be damned if that wasn’t a great example of incorporating ingame drops into MMO RP.
