Not OP, but I code Summertime Saga. You have no idea how much work it would be on sploosh's, catbug's, and my part to implement all the little interactions that could and should happen between the different characters. We do add little changes to dialogues here and there, but we can't do everything for each update, they take long enough as it is, and we want to release fairly regularly.
All those minor additions will be done as part of the beta for Summertime Saga, it's just polish, and as long as all the stories are not wrapped up and final, we could make polish additions that would end up being scrapped in a later update, we don't fancy working for nothing, you see.
