I think Erica does have enough of a personality. She is halfway between a "voiced protagonist" and a "blank slate", meaning that she does have a few fixed personality traits, while the rest is up to the players.
That's for sure. I am just not a fan of walkthroughs personally, but I understand how useful they can be.
I do have a ton of ideas for future games, so I wonder what I'll end up doing. Well, at least short term it's just Caliross and TOTDC 2.
Well, everything can have a final repeatable scene, of course. I just planned for the fairy queen to be a one shot, but I'll think a bit more about it, in case I change my mind. I think it also makes sense for the carillon content to end there, but as I said I'll think about it.
I mean, overall we have a few dates and 4-5 scenes with Tania. She isn't at the level of the more fleshed out characters, but I think it's good enough for her arc.
Once you reach a critical mass of mind-controllers, I feel it's better to leave some of them without any "grand schemes" of sorts. I am going to double-check Lady Rosa's content before the final release, but there is a good chance I won't do anything major with her.
