This is absolutely a real game. It does require at least a mid end machine to use... and a large hard drive if you want to download free scenes.
Probably one of the absolute BEST VR games as far as NSFW VR goes. Controls can seem overwhelming... but that's only because you can literally do about anything in this game so options take time to know them all.
I bought it when it was on steam, might buy it again here. Definitely interest piqued. If only OP would discuss the update options/time-line.
