As said above, the H-game part is more like a 'plus'. The card collecting is what draw (ha!) me to the game, with a plus also to the multiplayer interaction.

My main reason: boredroom really:P
Started playing LOV and i am playing it to this day, when Aigis came out i tried it but decided it's not for me. When Pero came i tried it and was sold on animated sex scenes etc... shame it's all censored and becoming really obvious cash grab but i still do enjoy it
