Quoted from OutpostKodelia:We considered that some people might not like that there and we debated on what, if anything, it should say. Without text there, a) it's less clear what these represent to someone who isn't familiar with the mod, and b) without something there it would be empty space because I need to keep most of that area to make room for the molex plug hardware on the back below the lights. The impact on cost is trivial, so it really isn't a cost decision either way. We could go with more of the abstract steam-punkish artwork, which solves issue b, but not issue a. But if anyone has ideas for what it should say, we're open to the feedback.
I agree about the writing not being there. It doesn't say anything on the playfield so why on the sign. I would like to see more theme related like gears and such. Add me to the list.
