"This all revolves around the idea of this new Glyph system, which will have you building up things as you go along. In the Glyph system, you will build up magic, weapons, and a variety of other things along the way. The thing is that you will not get a lot of these till later in the game. What this makes though is for a very fun second play-through.
As for the longevity here, there are plenty of reasons to keep on going, such as playing through a second time with new difficulty modes, as well as other bonuses.
I am going to try not to spoil anything for gamers, but there are some great modes as well as an online gaming mode for you to play with. One thing I was a huge fan of is the Boss Rush mode, don't worry you'll see once you play it.
Castlevania Order of Ecclesia is a must-buy on the Nintendo DS, there is no other way to say it. The game is beautiful, extremely deep, and is a blast to play while posing a major challenge. An absolute gem on the Nintendo DS!"
