Thanks for the recommendation, but now I realize that I should have listed those I played already, including Realm Invader, the #1 on my list XD.
Played both Caribdis' AVNs, Projekt Passion, Four Elements Trainer, Unraveling August (at least these are those I remember).
I love AVNs with a good story, but mostly those mixed with comedy are golden for me. I'll keep searching for these hidden gems.
