I prefer 1 x 1 to Group, generally because there is more room for character/lore development, and coincidentally even though it can be slow sometimes, all of my 1 x 1s are still running whilst every group RP I've ever tried to join since joining the site has petered out and died within 2-6 months :lol 

I'm most comfortable putting myself at a Mid to High Casual label, though I can and have done some pretty Advanced level posts with the right RP and setting. I like lore and character building but I hate being constrained to "must have this many words and nothing less" that tends to be assumed within the Advanced community, so I would rather stick to High Casual where I can get my lore/character fix and not feel like a chump if I have to drop my replies down to 2 or 3 paragraphs every now and again :')
