I'm actually glad lock-on is gone, and I feel that the combos feel natural.
However, some more depth could be added to the Style Meter and the Mission Rating.
Overall, the story is fantastic, the gameplay is entertaining, and I'm very excited to see all the new possibilities.
Also, I am hoping that the original series will continue alongside this new DmC. It be great to see Capcom and NT take turns between development. (DmC, DMC5, DmC2, DMC6, etc)
I think they could have added in a bit more depth by adding double-forward inputs (Stinger's) on the Special move key as well, and maybe some back-forward inputs, although those may be a bit too much..
