yea IGA should have dedicated LOI to Sonia Belmont since CV:R was canned.
her story didn't need a lot of rewriting, and Sonia as lead protagonist is better than the usual dude rescue the damsel trope that's overused since the 8 bit days.
well anyways this Sonia project is looking awesome, and she's epic in Serio's Castlevania Fighter too.
though yea Castlevania adventures type of game have more interesting level design and stuff.
a Castlevania II type game featuring Sonia would be cool too, or with character select like HD and Serio's has, except its open world like CVII, and like nonlinear progression, with mansions and bosses and towns, townspeople and stuff.
