I feel like constricting a person to only one character while realistic; is kind of a rough way to run the game. If it was releasing all at once, it'd be fine, but doing it update by update runs into this problem hard. People who are on a specific characters route can go months without getting *anything* in their corner. If it's more harem based, at least if your favourite character doesn't get an update, you still get *something*.
I know you can view the new content in the gallery even if you didn't go that way, but it feels more like looking in through a window to see a family eating Christmas dinner; rather than actually getting any for yourself.
