what are some good adult games that you only pay once to play? some examples are Bonetown(http://bonetown.com/index.php) and Activedolls(http://activedolls.com/?section=home&lang=eng), which i already have.

I kinda liked Nightstud 2, the first version is also not bad, but imho not worth paying for.

Just type in Nightstud in google and you'll find their homepage with NS, NS2 and an add-on for NS2 (you can download demos)

By the way, for some reason my antivirus went crazy when I downloaded one of their games, so BE careful

I enjoy the Nightstud games too, pretty cool, i just can't stop playing NS2

And no virus problems here, i'm using daily updated kaspersky.
