I am going to be honest.
Most western eroge game or rather eroge games with a more realistic looking style look uncanny to me. Treasure of Nadia however has a ton of hot af babes and is one of the best eroges I played.

Now this. This is peak eroge gaming (Especially with mods). Infinite sex with the waifus of your dreams any time. Probably even better with VR

Probably the best eroge visual novel out there (maybe it's sequels are even better). Lots of big booba and nice scenes. Couldn't get enough.

The Greatest Masterpiece of all time
