I"m playing Ninja Giaden and NG2 again for the fun and achievements (respectively). Although NG2 is vastly inferior to it's predecessor, it's still a solid title.
Unfortunately, it's basically the only action game series I've ever played unless you count ARPGs and platformers. What else is out there, and more importantly, what is out there that is also good?
I did play god of war and I didn['t dislike it, but I preferred NG easily.
What about devil may cry? I've never touched one before, or the 3d castlevanias? Or something else that I haven't mentioned.
