might have too many microtransactions but i can recommend arcaea and noisz starlivht. both are free to play with no ads.

arcaea has you paying per song, while noisz has a paid club pass which just makes the game faster to grind.

noisz is a bit mature, mentioning sex, transphobia, awful parents, quite a bit of violence, etc. and is also gay as hell if you do end up picking it up.
