In all fairness this is more a 3.5, and as I don't think this is a 4 to me I preferred to lower it down to 3.
I liked the premise of the game, and allows you to work it with the factions you like. The mission system is not bad but I don't like that much the timed ones, never liked them in regular games even less in an adult game
However, some things don't amuse me that much, first is one thing that bothers me in several of this type of game, time specific events forcing to a kind of grind at a certain point to return to that part of day or week. Than I don't understand why some basic actions skip a time of day. Why would giving something to a character skip ahead from morning to afternoon, were they assembling the gift with glue?
Then for some reason if you go to a location in the base but don't find there the character you wish to it blocks you from returning there.
Also, but this is just my personal taste, would like a more balanced approach on the girls bodies, now is all giant boobs and almost all athletic, I know is a fetish to some, I would enjoy some more balance but is my taste only.
The 3 rating is then more based on my personal taste on some details that just removed part of the fun in this game for me. But if none of this bothers you there is no reason no to try it at least.
