You’ll find that in queer culture, there’s not just top/bottom but a wide spectrum to define or describe preferences; I’m sure this all also applies to the BDSM world as well. There’s a variety of tops and bottoms and preferences like Bambi lesbians who don’t want sexual dynamics beyond cuddling and kissing.
I think these types of games would be a great place to start; maybe even something like Inscryption since it shows how deep games can be even when they appear to start off fairly simple.
