i've been a fan of shark for a while and i can't pass the oppurtunity of getting in my input on this one. having played all the games (more than once) here is my humble opinion
1. Sensual experiment - simple and to the point (love the seduction part, girl on girl action and dead ends)
2. Horny afternoon (especialy 3) - great storylines and very creative and diverce scenes
3. Sectret fantasy dreams - grat stories, can't go wrong anywhere though
4. Desire and submission - best in chalenging the player, awesome graphics and dead ends not in SM or domination
