In general and not just SF. Basically the same concept as the channel was before the SL videos. Showcasing muscular female characters in gaming (modded or not). The channel currently feels like an art project, everyone involved is just so dedicated to creating something. I don't want to dilute it with long gameplay videos.
If that's the way you feel, then yeah, put them on another channel. I just bring it up because ripped-pixels seems to be struggling to do videos himself, though if it's due to indecision or technical problems I can't tell.
