Dawn of sorrow was a fun game, but the story was pretty lame and I hate how playing as Julius is lame too.
Julius was awesome in AoS, why the hell did they reduce him to what he is in DoS! pisses me off. 19 year old Julius better be Simon x100.
The ending in AoS where Soma becomes Dracula is the best, and should've been canon. We all agree to this
I think there's still a high chance that another 'Sorrow' game will be made. Both games got relatively high scores and reviews, they are IGA's babies (he gave birth to them, and he loves them)
Hopefully the next potential game will flesh out the story, maybe introduce a new unique possible avatar for Dracula, reveal Alucard's ultimate fate, or Julius or another hero ending the legacy of Demon Castle forever.
Oh yeah, and also:
