Everything Becomes Waifu

Turn-based battles run the show here, with old-school JRPG combat standing in for whatever else this genre usually offers. You find Waifus, fight them, and capture them instead of killing them off, which is the whole joke.

Once caught, they join your party, and the loop becomes discover, battle, recruit, repeat, with your growing harem serving as your actual moveset. Seduction gets treated as a skill to master rather than a cutscene, folded into the same systems that govern your fights. Monster girls, milfs, and the odd possessed or paranormal encounter round out who you're up against, but the structure stays a straightforward RPG grind dressed up in innuendo.
