Hi, Cortez- I remember seeing you on the Gorums! Welcome back!
What's different? Well...I'll give my take, but take it with a grain of salt because I honestly haven't played much in SL Gor in recent years, just dabbled a bit briefly in a few sims before getting bored and wandering off or else seeing someone being an asshat to someone else OOC and getting bummed out and slipping off to avoid drama and people being ugly to each other OOC. So, to my admittedly slight experience lately, the RP is either so dull and predictable that I can't find anything worth giving up my limited free time for, or else people are acting so ridiculously shitty to each other OOC that it's like being in highschool again and I don't have any patience for that either.
There are standouts, almost every sim has a few people who are nice OOC, fun to roleplay with, and welcoming of new people or people they don't know. I've been lucky enough to chance upon a few ever sim I go to, and I'm always grateful for any fun bit of roleplay that comes my way, and new friends made along the way, but it does seem like these days, the roleplay is geared towards people who are quasi-lifestylers (who often consider themselves straight roleplayers, yet still treat people differently according to the role they play), who have hours and hours every day to be on sim and interacting with people, and who have their own group or 'family' they play with almost exclusively. If you're a single roleplayer without a clique or 'family', and don't have but an hour or two a few nights a week, it's really hard to get anything significant going in roleplay.
It's not impossible, though- my advice would be check out some sims, hit people up you'd like to roleplay with for ideas on how you could jump in with them, try to plan some stuff out with people when possible (unless you have a lot of time to allow things to develop organically), and jump in, try something out- if it doesn't work, reroll your character and try something else.
If you're of a lifestyler bent, you'll find plenty of sims and players of like mind to fall in with. If you're a straight roleplayer, you may have more trouble, but if you're open to compromise, you might find places and people to play with. I think the key is to find people of like mind, that you like playing with, and get 'in' with them, whether a family, faction, group, etc. unless you have a lot of time and don't mind wandering around till you run into someone what will roleplay with you. Whatever happens, best of luck! I keep dipping my toes back in the Gor setting as well, there's still something about it that I love, and there are still a few good roleplayers in almost every sim, but overall things seem much more insular and standoffish than they were in the past, so it's more of a chore to get any good roleplay plots going. One definite plus, with all the new mesh stuff, people overall look much prettier, builds are generally more interesting, and there are a lot more possibilities that we didn't have with prims/sculpties.
