I also note that IGA wasn't a huge fan of using the Belmonts as playable protaganists because he apparently felt the whip was a play style in danger of becoming stale, as a real world explanation for the lack of Belmont butchness.
Harmony of Dissonance had one and so did Lament, but Aria, Curse, Dawn, Portrait, and Ecclesia all dodged it. HD had several, but as a spin off entry, it doesn't really count. If a Belmont was playable at all, they were a bonus unlockable character as a reward for finishing, with only Dawn daring to give a playable Belmont an actual storyline for his mode (such as it was-- but it was freaking awesome). Worth noting that Circle of the Moon, a non-Iga game that kicked off that series of Belmont-lite games, also dodged a Belmont protaganist (but had other reasons for it).
