Have you ever heard of a "feel good" game? Y'know, a game that leaves you with a fuzzy wholesome feeling? Yeah, usually hentai games aren't quite that, but they still make you feel good. In a not so wholesome way, of course, but you still feel good about playing it; you had FUN.
Qualities might include:
Good, fast, balanced/in you favor combat. You don't feel frustrated or annoyed by the combat. Even if you have to grind for levels, you don't mind it really.
A storyline that, either in a good or bad way, ends up with the hero/heroine enjoying what's happening. Sometimes they learn to enjoy sex, sometimes their mind breaks until they enjoy it, but either way they don't hate it the entire time.
You also have choices! YOU influence how the story is going, even if you can't change the ending. Choose whether or not you fuck this person or not, that monster or not, or choose whether or not you, perhaps, pay debts with your body or just money. If you don't have choices, how can you possibly call it a game? That's, at best, a visual novel.
Awesome sex animations and visuals so that when you DO see sex scenes, whether through losing battles, getting surprised, or choosing to fuck people consensually, you actually enjoy them and can get off to them. Of course, for games that are text based, you could replace this with amazing descriptions instead, but the point stands.
Now, stay with me here, what if you were to take ALL of those awesome things that make a game great, and completely strip them away? You would end up with Bard Trainer.
In this game, you play through excruciatingly slow and frustrating battles (No, there are no options for changing animation speed), you watch various stuff happen to the heroine with ZERO choices along the way, you see some mediocre sex animations, and then you eventually quit before making it to the end, because why would you keep playing this game?
Now, the IDEA of the game is great. Your father got kidnapped and you have to run the tavern to pay off his debt? Cool! Mafia that offers its "services" to keep you "safe"? Also cool! Conflict with rivaling mafias and thugs that want to use you and your tavern for profits? Amazing! Are any of these expanded upon in interesting ways? Absolutely not!
The only consistently impressive things about this game is its ability to underperform and an absolute refusal to expand upon any of the most interesting parts. SO much potential, so much disappointment.
Needs:
Better animations, better writing, better storytelling, better battles, better almost anything. Oh, and if it was also a game, and NOT a "watch the story and do some boring stuff in between!" it would also improve immensely. 0/10, can't give it 0 stars out of 5, but trust me when I tell you that I want to.
