In its complete form probably one of the best Hentai Games out there. Tons of Quality Sex Scenes with different dialogue depending on the Maids Personality, VR with full Camera Control which enables you to view the Scenes in 1st / 3rd / whatever Person.

People actually interested in this game should probably take a look at the Japanese Version as it has a lot more Maid personalities, sex scenes and general functions. My current Japanese Installation is sitting at 77.5GB (154GB if you count the connected content from CM3D2) whilst the Steam download is not even 5GB. Should show the difference in content.

The game feels like the Yakuza of H-Games. Tons of Minigames like Karaoke, a Casino or "Vacation" Mode.

The base game on the other hand is rather lacking. You still have a good amount of content but the GP-01 Addon adds a lot.

18+ patch is available via the Publishers Website for $5. People should look at the prices for direct 18+ versions before complaining about having to pay extra ($45 on both Nutaku & directly via Publisher). You're actually saving money here.

Pros:
+ Catgirls
+ All Catgirls
+ Animated Catgirls
+ (Mostly) Good Animation
+ Cute Girls doing Cute Things
+ ご主人様 の エッチ！

Cons:
- They aren't real
- Teleporting Cake

Should you buy it?:
Animated version of the NEKOPARA Vol. 1. If you really liked the first "game" or the series in general buy it.

Side Note:
I've paid 165€ to get the Limited Edition of this and my parents are very proud. :^)
