Here's how I'd do it.
Instead of genre "tags," I would just define Free, Casual, and Advanced somewhere (which is already done), and let those be the tags for games divided by genre.
Go look at the 1x1 interest checks, for example. That is a very wide array of genres right there. You'll see [Free], [Casual], and [Advanced] quite easily. None are really drowning out the other, and if they do... then that's what a Bump is for. Perhaps interest checks in one part of the forum or the other occur more frequently, but the more they are divided by genre, the less that will show. Remember that as it is now, all the genres are lumped together.
Also, it has always seemed to me that separating a forum by supposed "skill" levels is just begging for tension between people that identify with those levels. i.e. I am a Free RPer, screw those novella-writing elitists! I am a Casual RPer, screw those noobs and elitists!. I am an Advanced RPer, screw those one-liner noobs! (Some exaggeration and generalization here. It's the small minority around here that makes such things an issue, I know... but still. The site setup encourages it.)
And to me, having the Free, Casual, and Advanced tags (rather than the sections), would encourage people to um... not identify quite so much? The difference is sort of subtle, I know. But I think it would encourage people to think more as such: "I am simply a roleplayer playing in a Free/Casual/Advanced game in the <insert genre> section."
Also, this leaves room for those that don't identify with the Free/Casual/Advanced thing at all to just put up an interest check in a particular genre they are interested in and define their own expectations in the interest check/OOC.
I would breakdown the categories thusly:
- Futuristic (for the sci-fi and future post-apocolypse type games)
- Modern (define a starting time, say... 1900's to present -- where the slice of life, highschool, super heroes, etc. could play)
- Historical (any time from cavemen to 1900's, alternate histories included)
- Fantasy (sword and sorcery stuff)
- Fandoms (obvious)
- Other (Sort of iffy about this one, but... for things that fit nowhere else)
- Tabletop (namely because a whole thread of people asked for this not too long back)
Naturally, the next argument to this is, "But some things fall in several categories!" Okay... well. Presently, some Casual games could be Advanced games. Some Free games could be Casual games. Let the GM decide where he/she wants to advertise... and if they want to advertise a Dragonball Z game in Fandoms, Futuristic, and Fantasy, who cares? Maybe they're interested in attracting people that love those things. Leave the responsibility for deciding where the game fits up to the GM.
But all that aside... dedicated roleplayers will root out roleplay, whatever you call it or however you divide it. I think this site succeeds because it's organized, simple to join, and it doesn't have a bajillion different windows and dividers and such in the screen like some of the other sites I have glanced at. As long as all that's not screwed with, the breakdown of categories/genres/whatever doesn't matter all that much, in my opinion.
