You know, I thought I had made a post in this topic because I had started writing one a few times. I'm a fan on Ninja Gaiden. I think it is interesting, in that the storytelling in the NES games was amongst the best on the NES, and the storytelling in the new games.. is awesomely bad. I love the gameplay of the new ones, but the NES trilogy's story is way better. I'm curious to see what direction Ninja Gaiden 3 will go.
As for the new series, I've only played the Sigma remakes, and although Sigma 2 is a high quality action game, I don't feel it compares to the first. They traded too much style for substance. But I do love the tonfas! Those things are pure badassery.
If anyone that has Sigma 2 wants to play team missions with me let me know. I'll need to play the game again before, as I haven't played it in months and will be rusty as hell, but if you want to we can make it work.
