Well a few thoughts: The okay, the bad, the good.
Okay: The updated Cass scenes are pretty decent. Some seem wholly new, while others seem like slight upgrade/sidegrades.
Bad: I know Cass is supposed to be the more muscle bound one, but she feels like she is missing something that makes her more attractive? Sometimes personalities are enough, but currently the only personalities that boost a character are probably Tina (Tina ugly af, but she fits the aggressive bull arch type so she can be 'attractive' purely based off her personality), and alittle bit Montana/Anita. Feels like Cass could've been boosted by their more kind/meek personality, by allowing aggressive player/player gf actions. For example Cass is one of the original characters to get a dinner date, but outside of letting them cook, there isn't any special scenes. Feels like it misses out if the MC is really horny, or the MC's girlfriend, they should be able to pressure Cass into further sexual actions. Whether Cass is cooking, or sitting at the couch.
Good: Probably brought Cass up to the level of the other girls. While Darcy is still slightly rough around the edges, and samantha is honestly a character I ignore 99% of the time, Cass is finally up to par with the other scenes now imo.
For those on the fence, this is a good update, but only if you liked Cass. It didn't add really any new events, it either expanded, cleaned up, or made variations of the same events already possible, but with much better dialogue to boot. Feels like super horny MC/GF actions should occur, or possibly in the future Cass' meekness should be exploited.
