I actually got Encore of the Night when it was a dollar (dunno if it still is), and it's really not too spectacular; in fact, it's pretty boring. Also, other than Alucard's redrawn graphics, sprites are either just left magnified or "retouched" to look like 2xSai trash (Richter in particular took a big hit), but for a dollar I can't complain too much.
EDIT: IMO, it's also a HUGE missed opportunity to finally give Richter some sprites that actually reflect his official art.
