I would very much want to see in Otome Games the struggle to get the one you desired to be with, not just a little sweet talk and then BAM they're together. Something like Steam Prison but with more challenges and hardships, 'cause real love is not easy to achieve
I'd like to see smart, cunning characters, especially MC, with ambiguous morality. I'm too bored with naïve, kind, cheerful, or optimistic MCs these days. Actually, it'd be awesome to have villainous MCs for a change (✧ω✧)
Also, I'm deeply in love with logic puzzles, mysteries,, abstract ideas, or anything that flexes my mental muscle, so it'd be wonderful to see more intricate plots with intellectually stimulating gameplay. I haven't seen what I so desire in any Otoge, but Ace Attorney 3: Trials and Tribulations is a good example.
