@egg Gotcha. Maybe Arx isn't a fair comparison with other games that might not have such a large playerbase and engaged staff. All I can say is Arx staff give a lot of tools, lore and opportunities for players to create adventures themselves, their characters are pretty well fleshed out with established relationship webs, hooks in present situations and they're happy to update secrets if you're feeling still hungry. I like that.
I think you might find some luck at Arx with that type of RP, if it leads to you forming sort of an adventuring party (think D&D with a diverse party base such as wizard, warrior, thief instead of all warriors) to do some fun things later on too. Check out the +where, see those who have lrp on and instead of saying no, just go out and directly RP with them.
I've been enjoying random encounters and a some of them have blossomed into solid regular RP that I look forward to and I'll go out of my way to RP with them again.
@egg If you're on Arx and ever are looking for a scene or RP that isn't just sitting silently sipping a drink in a bar while giving brooding eyes, send me a message and I'll send my character your way. You can join Arx here.
