I personally would highly recommend these games, but you need to understand that going into them they are very linear so if that’s not your cup of tea then I wouldn’t recommend them. The story, while very well written and very enjoyable, will play out the same everytime you play with only slight variations.
The real choice is in your MC. What kind of person they are, how they react to things, how they feel about others. The MC for SoH is kind of their own character that you get to put your own spin on it. I would not recommend going into the game with a set idea of what your MC is like. Play the first game and let the game help you shape them.
The characters are all very interesting and their relationships with the MC are probably my personal favorite part of the game.
There is a certain anime esthetic to the world, the story, the characters, and the plot and if that’s your cup of tea then go for it, and even if it’s not I would still say it’s worth it.
The game really reminds me of watching an anime but with your character as the star. If that sounds good to you then yes. 14 dollars all 3 of the games (which I believe still has 4 more games coming out) is a good price.
It really just depends on what you want from your games. If you want a really open story with lots of different paths (like Choice of Robots) then I wouldn’t recommend them, but if you want a really good story with a main character that you will grow to really care for then I highly recommend them.
Edited: I also want to mention that the games are all a good length so they are worth the money in terms of how much you get out of them.
