It's been a little while since I've been in an RP with anyone other than my girlfriend, and I'd like to get back into it!
Here are a few things to keep in mind.
I do not do fandom RPs. Nothing personal against them, I just have trouble pretending to be someone else's character. The only way I will consider it is if you play those characters and my character is original, but even then I may not accept.
I like to think I have decent grammar and I would like someone with at least a similar level. I do have my own grammatical issues (using too many commas and sometimes making run-on sentences), but just keep that in mind and try to do your best. Understand that I am not the best, but I am not bad either. If you can tolerate those few issues I have then great! I like to think my content makes up for a few little errors.
If we're using skype (my preferred method) or something other then notes then I am more willing to let smaller posts slide due to how quickly we can each get them out. If they are in notes though then I expect posts to be at least a few good sentences long since it will take a bit longer for responses.
There does not have to be sexual content, but if you are 18 or over then I do not mind this. My RPs can range from extremely light to very dark based on what my partner is comfortable with so just keep that in mind. All the same, there will need to be a good chunk of story before anything like that happens.
Obviously, no godmodding. Try to avoid Mary Sues as well. I know it can sometimes be difficult, but understand that a compelling character needs to have a wide variety of good and not so good character traits. Even when I use actual gods, they have their own problems and weaknesses!
I believe that is everything. When it comes to the kinds of stories I do, I have a wide variety. Everything from sci-fi to fantasy and everything in between. I have a few story ideas if you're drawing a blank, but I'd love to see what you are interested in as well!
