I check the number of reviews the game has. If then are too few I wait for more to see if the score goes up or down more. The more reviews the better chance the game could be either good or bad.
I believe that you don't need sex scenes every update or in the erlier chapters. That being said some spicy content every update is a must. That way it can build up to hopefully a more meaningful sex scene.
I think that sometimes animations are not needed. Other times they are. If animations are done right they can improve a game greatly, but if done wrong they will ruin a game. So a game not having animations is not a deal breaker for me.
An amazing game. Update evertime a new update drops because the game is getting big. After updating I sometimes wait for the next update to have maybe twice the content to play. Story keeps me playing.
