In reading through the forums, it seems that many people are inspired by mechanics or will build games around mechanics, and then put the theme over top of that once the mechanics are worked out. To which I say, "Huh?"
I can't quite wrap my head around that way of working. Maybe it's because I'm not an experienced designer, and I'm not aware enough of the ins and outs of different game mechanics. Maybe I'm just a theme guy. I've got a couple of games that I've been developing for a while now, and with both of those, I took something I found interesting (in one, a sport, and in the other, the behaviors of corporations in the marketplace) and said "What are the compelling aspects of these things and how do I recreate that with game mechanics?"
Neither of my games has gotten to the point where they really engaged people - basically the response has been "it wasn't bad," but it's not something they'd ever pick up again on their own, which to me means that while the mechanics might not be "broken," they're not refined to the point where they engage people and create interest (and the games are probably bloated with unnecessary mechanics, too). Sometimes I wonder if I get so hung up on theme, I'm unable to take a look purely at the mechanics and make decisions purely on what makes for good game play.
Now, while I let ideas for my other two games percolate in the back of my mind, I think it would be fun (and beneficial) to try and design something simpler, with a less complex theme. My problem is that all the themes I can think of are played out (or they're ones I just don't have any interesting ideas for). Since my goal is something simple, maybe it would be best to start with a central mechanic and work out from there, but I'm not quite sure how to go about doing that (though I would like to learn).
I'd love to hear how other people work and what gives them inspiration. If your a theme person, where do you get ideas for unique themes (I know they're "all around us," but maybe something a little more specific would be nice, just to see how other people work). I particularly want to know how the "mechanics first" people work. What mechanics inspire you? How do you go about building and refining mechanics without a theme?
I know this a topic that is often talked about, but that's probably because it's perennially relevant. My apologies if I'm just rehashing the same old, same old, but this is something I'm intensely curious about.
