Honestly, I played recently, mainly because many people said it's similar to other already mentioned games. And I just dropped it completly in the same day. I feel like it's a much different experience than when you play something like NTRaholic, although this is obvious the moment you start the game.
Without jumping on the game to someone who seems to like it, the main focus seems to be the story and this is not usually the focus of games like NTRLegend. This is what leads to many praising it for being a much more "slow burn" type of netori game. Problem for me was that the gameplay loop is very boring and if the game progresses slowly....I did advance significantly the "post-training" events for a character and outside the story moments, it hardly changed the interactions or h-scenes for me. You really have to be interested in the story to like this game, otherwise every one of the mentioned NTR games beats it in the art and animation departament by quite a mile.
