None of my business, but.....
Loren is a pretty major game, plus there is an add-on to do as well - Chambara awaits! There is still the possibility of a followup to Planet Stronghold which will also be a very involved game. So trying to do an RPG for Bionic Heart 2 would probably make you crazy and cause you to quit, and become an ice cream salesman.
The Heileen series seem to be more visual novel and you will be releasing a new one this year so the visual novel side will be covered.
Your dating/life sim games seem to do well and also appear to be quite a bit less stressful than the RPG so I would guess that the dating/life sim is the way to go.
I really like Spiderweb software games but they only produce two major ones a year and the second one is an updated version of an older game. Basilisk games seems to only get an Eschalon series game out every couple of years and Hanako games which is a more similar style to some of your dating sim games does not produce nearly as many games as you. I really like the way Loren is evolving and it is becoming much better than Planet Stronghold - which is still a really good game and people should buy it if they already haven't. I'm trying to say you seem to have started several series that could almost be thought of as franchise games but you may be running the risk of burning out by trying to push too many games out the door in a year. I think we saw five last year and Loren is your second this year.
