Rio is Rio, but i don't find this bad, it's better than Kunoichi Ayame. I give you a point abouth CG, there aren't many but their are dinamic (based on the type and number of enemy)
I'm Hyped for a new Rio's game
It's not really about CG. Housegame is always going to have great CGs. One of Housegame's best features is really creative and sexy situations that often center around the MC getting in over their head and getting into deep shit.
In this game, the variation in sex scenes literally just came down to "you have xx zombies next to you of xx type." There were also only like 4 different enemies and every single sex scene was just a combination of different quantities of them.
Compare that to something like Exorcist Rio 3 where you got her daily corruption fuck session at night which slowly ramps up against her will, you got aphrodisiac gas chambers, you got tentacle pot monsters, you got ghouls jumping her in the jungle, you got bugs dropping down on her when she walks into the wrong cave, etc, etc, etc.
I do like the action combat from Kunoichi Ayame the best and I'm curious as to whether or not we'll get a Rio Action Combat game which hasn't happened yet. I actually really liked Kunoichi Ayame a lot, only being outclassed by Rio 3 in my mind (and Rio 5 being a close third) but different tastes I guess.
One thing that Panacea-Z did that I'd like to see though was a recurring random encounter super-boss that you repeatedly fight. If he could push that further in some future titles, I think that could be pretty cool.
Housegame's a genius though so I have faith either way.
