The game that started the series
I'm impressed because the NES still stands out today and Konami released this retro goodness in 1987. Most Castlevania enthusiasts will enjoy this game, some might not like it but will faire with its gameplay, graphics and storyline. NES and emulator owners will appreciate it for being in their string of NES titles for years to come.
Castlevania is one of those game where you sit back and relax in the darkness of your own living room with good 8-bit music, nice action, and great vampire-fighting gameplay. Need I say more about this game? Just play it.
