Sweet mercy! Have you been playing an E(rotic)RP?
Not purposely >.<
In general, there are a lot of possible rule sets. Rules light like d6 basic or microlite20, and heavy simulationist ones like AD&D. There is a Sailor Moon RPG book which is a long read, but where a trained veteran soldier can fill up Wiseman with enough Heavy Machine Gun shots that not even his plot crystal can bring him back. (But defense rolls, and combat in general is broken, so meh)
Oh okay. So is there a specific set for the roleplay corner? Or is it a specific set of rules per thread? What are the main things I need to know before I start roleplaying?
How would your ideal RPG look like?
Umm...I have no idea what you mean?
I'm sorry. I'm a complete newb >.<
No problem, you're doing well.
In the roleplay corner, it's a per thread and a per-person thing.
Some like to treat it as a collective fanfiction writing project, which means no rules, and essetially full creative control for each player, except there isn't much playing in it. This is called freeform, or collaborative writing.
The classic form of roleplaying games, evolved from freeform, is having a game master/storyteller who controls the world, and the players who are restricted to their own characters, and telling the GM what they want/try to do. In this form the GM makes all decisions, usually aided by a set of rules. When there are no rules except that the GM has the final say, it is very much a freeform game with a GM. Ruleless works best when used in stories set in IRL history, and for rule-assisted versions, there are all the systems that I'd better not list here.
Generally you can find out what kind of an RP is by looking at the OOC/Discuss/Signup threads (ooc stands for "out of character", which is where the players can talk about the game as themselves rather than their characters.) If there are no rules listed aside from no metagaming/godmode-ing, then it's a freeform and you'd do better to avoid it. If someone DMs (Dungeon master=Game Master), it's generally okay.
