Alright, so I'd like to offer up some of the modifications we've made on EpicAdvice.com to the Gaming SE if the community would be interested. Most of our modifications are pure JavaScript modifications to the SE Engine (1.0) that should easily carry over to the new 2.0.
The primary one, if the community is interested, would be a "Level Bar", a common Video Game concept. Lots of games that involve character progression include levels, or "Reputation Levels", which is what we've implemented on our StackExchange. It fits perfectly with our World of Warcraft theme, but could easily apply to a generic video game site. Basically we took the reputation needed to earn the highest level of moderation powers on our site (10k), and made that the "Max Level", the last obtainable level, and created a scale of reputation required to earn each level.
The reason I propose this, is we believe (at EpicAdvice) that integrating more "Video Game Themed" elements into the site (less programmer-ish) with the goal of increased interest and involvement. On sites like SO, reputation earned is a sign of accomplishment within the field. For video games, the common sign of accomplishment is Levels, which is why we choose that route. It's all about catering to your audience and making them feel at home :)
Here's a quick screenshot I took as an example, with my current level being displayed.
If you'd like to view it in action, simply register for an account on EpicAdvice and login. You will see the "Level Bar" appear embedded within the logo, stating your current "Level" as well as how much reputation you need to advance to the next level. We have a few other things we plan on implementing with this, but haven't gotten around to completing yet.
I realize the design for this site hasn't been completed, nor has it even left Private Beta, but something to consider for the future of the site. If there's something else we've done in the past on EpicAdvice that may benefit the Gaming SE's success, we are more than willing to share the code.
So the final question is, would something like this be applicable/desirable for the Gaming Community we are building here at the yet unnamed Gaming SE? If not, no harm in asking. :)
