I also mention this every now and then. Another thing that would probably happen if Fujino updated in bigger chunks, is that Fujino might actually come up with more game elements instead of what it currently feels like; which is just a linear path CG hunting game. And there's not a lot of CG hunting to begin with since it's very linear. So basically Fujino would have time to develop their main story line, and side content at the same time. If not that, then at least they're more likely to finish story arcs every 2-3 months instead of mini chapters within those arcs per month.
As a side note though, Fujino giving out about an hour's worth of content per month is rather amazing all things considered.
