Not really. I prefer MC to have their own character. (I also favor them having their own sprite and voice actor if possible). In the same time - if I don't vibe with MC - I usually dip. So yeah, it's double-edged sword.
I think that I prefer the same core personalities, but now favor more mature looking LIs. So for me probably only looks preference changed rather than anything else lol.
Shinigami to Shoujo. Honestly, plenty great otome and BL games (still salty that Shingakkou will never see an official localization since budget issues) could use localization.
