Vampire Rain demo

I really enjoyed the VR demo. Sure it's a Splinter Cell knock-off with subpar graphics, sound and voice acting. But I played the stealth portion all the way through. I just may be hungry for another Splinter Cell because I recently started playing Splinter Cell on the DS, which is crap but I really like playing it. I can't wait for SC:Conviction. Has anyone else played SC on the DS or Vampire Rain?
