I orginally voted yes for this, and while I would probably buy it (as long as it wasn't locked to having to be online to play it like SotN on XBLA), I would rather see an updated SotN.....
Done by --->WAYFORWARD<---
Reasons? Well, I've played the original SotN so many times already that it's overplayed to an extreme (Still love playing through it once and a while though). Hell, they could do it in a particular order even.
Whenever I play through SotN as Richter, I always imagine myself playing as Richter first entering the castle, with shaft hypnotizing him at the end. I figure that the first playthough could be as Richter, with the second being Alucard or Maria (player's choice). Remake the entire Castle, add some stuff and revamp the original to play more according to bloodrayne's rules, just no stage by stage score of course. For Richter, WF could copy many of the moves from LoS, just do them in 2D. They could even, after you've completed the game, add time/point trials where-in you would be timed on how fast, and how well, you can get from the beginning of one area of the castle, to another.
Even better, make a new room containing some sort of device which controls the trials themselves. Perhaps a steam-punky/magic chair which you sit in, which allows you to do the trials in your mind. That way it would seem like a training exercise done by Alucard on purpose, and not just a videogame thing.
Anyhoo, I know some of you may think this is nuts, but I would rather something new and updated, than just the original that I've played countless times by now.
Now the only question is would we want to see something like this in BloodRayne's graphics, or old school pixels? Hard to decide.
