I have been a big Pokemon fan since the 90s, and have played almost every main line game since Red/Blue days. I thoroughly enjoyed the change to the original formula, especially the wild Pokemon spawn mechanics. Largely, the motion controls for capture were great but became less enjoyable in the later parts of the game where the Pokemon were harder to catch. The same old battle scenarios and strategy remain, and the colourful graphics and removal of HMs make it a joy to play. I loved it, and I hope we see some of spin-off mechanics implemented into the main series.
