The downloadable version of Konami's Castlevania: Symphony of the Night is going to break Xbox Live Arcade rules, by exceeding Microsoft's previously strict 50MB size limit.
In an interview with Gamespot, Xbox Live Arcade group manager Greg Canessa said that if a game exceeds 50Mb in size it's for a "very specific reason" that ensures that the gameplay experience is the best it can be.
"Castlevania: Symphony of the Night is one of the most popular games of all time, and you can [bet] that you'll see similar high-quality games come to Xbox Live Arcade in the future," said Canessa.
Seeing as Symphony of the Night was originally a PlayStation game - and not a 20-year-old arcade title like many other Arcade entries - it's perhaps not too surprising that Castlevania won't be zipping down our broadband pipes as fast as other titles.
As for details on port itself, it's sporting enhanced graphics and sound, widescreen support, achievements, leaderboards and all the other fancy Xbox Live goodies you'd expect from Arcade titles.
