That's not a club, that's a campaign. You don't need a theme for a club, you need a venue.
Me and my friend were thinking of starting a wargaming club. We settled on a ...
...place, the local community centre/church hall/abandoned shack at the edge of the swamp (delete as appropriate). We thought about meeting on a Thursday night/Saturday lunchtime/every full moon (likewise).
We also had an idea for a campaign, for the two of us who're first starting anyway, we hope other people can also join in later as we get more members. Here's the ...
...theme: an Imperial planet undersiege by Chaos forces, and the Adeptus Astartes came in to help (specifically, my dad's Blood Angels). Other forces were drawn in as well (the Tyranids). I was wondering if there was any other decisions we needed to make (other than a name, of course)
I see no problem with the campaign, it sounds perfectly do-able. I like campaigns, I think everyone should play like that all the time.
The club though, requires many decisions to be made. Where, when, who (you already know "what" - "a club"; "why" - "to play 40k" and "how" - "by meeting up and using rules, dice and miniatures"); beyond that, "how much (if anything) should we make subscriptions?" and "how do we let potential members know?" are the most important questions, as they most directly affect recruiting new people. The name is important (no-one would go to "the Really Dull Club for Smelly People with No Friends", for instance) but it's not the most
important thing you have to consider. That really is "where are we going to meet?", I'd think.
