I don't remember my first, but the first one that actually sticks out in my memory is Mystic Messenger. Since it's free, the choices actually matter in the game, and despite its messing up my schedule... I like 707 a lot TvT
I don't mind having a faceless MC since I'm self-inserting myself in most games. Which also means I don't like MC with too many characteristics. (Ơ vƠ)
For me, it's also the art as well, since it's the first thing you look at when you check out the game. And then... consider the abuse of AI nowadays, I also have to check to see if the art is AI or the script is written by AI. It felt awkward sometimes.
