What kind of room would you like to claim in the castle?

I would really enjoy a music room. Something that's got an organic upright...yeah that'd set the tone. Pianos can really make any atmosphere you want, ya know?

This is what I want....

I want the theatre area of the castle to have a special room where you can see the animations for each attack of the enemies in the game. Almost like they're performing for you.
Maybe you can unlock the animations by using an item like a "Theatre Shield" or something where the enemy has to hit you with the attack for it to be appear in the theatre room. Almost like Charlotte's shield in Harmony of Despair. Maybe the shield can have a special attack that teleports you to the room.

I'm a completionist so I for sure would go all around the castle capturing animations. It would be so much fun.

The benefit would be, the ability to rotate the models, zoom in, pause the animation and see the beatuful models without taking damage.
Mirror of Fate could do that on its menu, but the enemies were kinda dull. Also they just looped the same animation over and over. Its was pretty lame but it was better than older castlevanias just showing you a sprite.
That does't sound too crazy or hard to do since theyre using 3D models anyway. It would extend the replay value without being stupid like Justes furniture collection.

Maybe the specific enemy sounds can play for each monster too. I remember old Sound Test modes would play all these sounds with generic numbers as names and I never knew what monsters they belonged to and that was pretty lame.
