I don't really see a need for dice rolls or character sheets, since we're all mature enough to play for the fun of role-playing and building a story together (as opposed to behaving like rabid kids who need to prove they have the strongest build/pokemon). However, I think there should be some general guidelines to fair play and some rules to tell how powerful a character can be, so that we avoid "unpleasant surprises". I'm also in favour of an introductions thread where people shortly explain who/what their characters are (and it's also the place to post sheet-related stuff, if you think it's necessary). I already have a character I've been wanting to play for quite some time, I'll use her as an example of how you could possibly set up the mechanics part:
Nova Shadowstalker (obviously not her real name)
Level: whatever's good for you, but preferably between 7 and 14
Race: Sun Elf Fey'ri (but much weaker than the official DnD version)
High scores: Intelligence (primary), Dexterity
Medium scores: Charisma, Wisdom
Low scores: Constitution, Strength
Classes: Rogue, Ranger, Arcane Trapsmith [custom]
Strong points: Headshot, sneaking, poison, traps, battle strategy, DIPLOMACY
Weak points: Melee, fighting without preparation, uncooperative team
I'm not going to post background stuff here because it would take even more space, so I'll save it for the introductions thread if there is one.
