Now that I think about it, the story for many games peaked when it (and the game itself pretty much) had dark or very dark vibes, Tekken's story peaked at 3-5, especially with 4 which is the darkest Tekken game out of all, same with Senran Kagura, where Deep Crimson and Shinovi Versus's story is interesting to follow to a certain degree, even with MK, the Deadly Alliance-Armageddon era is the best story-wise imo.
