That's the other way around actually since this game is inspired from the light novels and animes, "it's so cool that all the abilities and those things are all in this game!" 😉
But are you not bored watching the anime since it is a teasing and blue-balling anime excluding all adult content offered by this game along with all other custom content added by PastryIRL?
I remember that the anime frustrated me to no end when I first watched it because Kazuma specifically mocked other animes' protagonists stating "I am not like those pervert animes' protagonists surrounded by women and never ever daring to actually do anything with them" only to be EXACTLY THE SAME which frustrated me EVEN MORE than other teasing and blue-balling animes because this one was hypocritical enough to openly mock other animes only to be exactly the same and which is why I LOVE this game here who is not hypocritical and is true to Kazuma's promise and even more because this is an actual video-game which balances adventures and actual RPG's gameplay with actual characters development and relationships building instead of being merely a porn visual novel which exists only for meaninglessly fapping, which is why PastryIRL is one of my favorite creators and Adventurer Trainer is my favorite Ren'Py game so far! 😆
