After having played 1 and 3, I'd say this one is the better of the two. Still things develop a bit too fast and some of the story is just too comical which takes you out of it for me. Also the english translation is not the best..but that was expected.
Having said that some of the scenes are really hot, especially the one where u get caught masturbating by the computer, wish the game was a bit longer so we could see how that progressed between MC and the wife, and not just see the end result. But I guess this was never supposed to be a long game.
And it's pretty obvious ada was not on your side the entire time, she is wearing a QOS necklace and her comments and attitude is glaringly obvious.
I tried finding the 2nd game in the series, but some people say that this is actually the 2nd one. they just re-named it to 3rd cause steam apparently rejected it the first time, so I guess they just changed some minor things and re-named it. Anyone that can confirm?
I'll for sure check out the 4th one when it comes out.
