@SerbanR No. Research into Affection has different models, different method of getting the girls to do what you want, and other slight differences so it is a different game. What is similar are using levels as triggers and the engine.
This game (Research in Corruption) focuses on subliminal corruption. Along with the younger-acting sister, it was "too hot" for Patreon to handle. So Boomatica couldn't continue it. Now DrSmith is in possession of the assets, the game, and ideas of what to do so he is continuing this game in his spare time.
RiA = Affection, More mature sister, different method of getting sexy times.
RiC = Corruption, younger acting sister, subliminal corruption via music and interactions.
