Out of the many early 360 titles I played back in the day, Ninja Gaiden 2 stands out as the one I had to return to and finally beat. Playing Dark Souls made me realize that playing a particularly challenging game can be extremely fun and rewarding, and I wanted the reward of finally finishing a Ninja Gaiden game. Before I had merely admired NG2, playing a few levels before getting frustrated and quitting because I couldn't get the reward of the end, but playing it again I realized getting good at the game, in other words the journey, was the real reward, and getting to the end was merely the culmination of the Ninja training I had mastered. Also boobs.
