Alright, that's the basics out of the way. Now, to go a bit more in-depth.

What version of orks are we going for here? Will these orks be the grim-dark war mongers of death and destruction type, or the goofy, dumb-funny joking type of orks? Are we going to be monsters like a large percentage of the cannon would describe orks as, or the joke that their codex makes them out to be?

As a group, will we have worked together before? Are we an existing mob that has been together for a while, or will we be just random boyz who decided to group up because we could?

How important will we be to the overall plot? Are we meant to be 'heroes' who are sent on missions that the bosses need done, and thus our final decision of who to back will carry weight? Or, do the bosses themselves each have a preset destiny in store for them, and who we pick just decides what kind of game we play near the end?

How are we going to handle group equipment? For example, if our mob has a truk, who gets to drive? Who gets to use the guns? Will we decide as a group what kind of equipment is on the truk, or will the one designated the driver be considered the 'owner' who gets to make the final decision on what happens to it? Or, will there just always be an NPC driving us where we need to go in whatever the plot demands we be riding in?

What about in-fighting? Orks are well known for vying for power, especially within their own groups. Will we be depicting the typical ork traits, and thus constantly sparing with each other? Will our group be special, and more effective because of a surprising level of co-operation? Or will there just be a nob among us who keeps us in line, and if so who?

How about the planet we're landing on? What kind of terrain should we expect? Who will we be fighting? It would be quite annoying to create a mek who specializes in looting enemy war gear, only to find out we're fighting tyrannids the majority of the time.
