I'm thinking about trading in four games (Baldur's Gate: DA, Buffy, PGR, Rocky) and $10 at EB for Ninja Gaiden. Of the games, I beat BG: DA, Buffy and Rocky and didn't really like PGR. I paid about $50 total for the games so I really wouldn't be losing out much. Besides, the only game I go back and play is Rocky and that's only for a fight or two. Before I trade them in I have some questions about Ninja Gaiden. There's tons of hype for the game but I'm unsure of a few things. About how long is the game supposed to be? I heard rumors that it's only about 8 hours. I know there are the original games (including the original arcade game?) on it but it would be dissapointing if the main game was short. I also heard that the difficulty is extremely hard by default. Is this true and can you change it? I enjoy a good challenge but from what I've heard it's supposed to be either insanely difficult by default or have that as an option. Most importantly, is the game supposed to be good? Hype doesn't always equal a good game.
