Why would you do that? said:
You all found Castlevania 64 long? I thought it was somewhat medium length. I actually feel Super Castlevania IV is longer.
Now Legacy of Darkness, I haven't played (though I would really love to since CV64 is my favorite in the series), so I don't know how long that is.
LoD has a lot more levels in the main mode, because the new main character, Cornell, goes through every stage from both modes from the original Castlevania for N64, plus several new ones (that is, he goes through every level in the game in order). However, Cornell's really powerful, so fights and boss fights are much easier with him than they are with the other characters. Also, unlike the original there's no time limit, so you don't need to worry about time when trying to finish it properly.
Once you beat it with Cornell, you unlock a second, short mode. Complete that and find the things in it and you unlock modes with the two original characters, similar to their modes n the original game but with a few changes.
It's definitely got more content than the original CV64, that's for sure... though even that one did have some replay value, with working towards getting the good endings if you took too long the first time, and with how there are two characters to play each with several exclusive stages.
Anyway, yeah, the first two Game Boy games were kind of short, but the first one was supposed to be a portable game and didn't have passwords or anything, so it made sense to make it shorter -- make it too long and people likely won't be able to finish it, given that handheld gaming sessions are often shorter than major-console ones, I think.
Of course a remake of it hopefully would be a bit longer, particularly coming on Wii, but a short, fun game wouldn't be that bad either.
