Faithful Remake to the original Fan Favorites.
Missing some features from the better Sinnoh game (ahem, platinum), although very well done.
Some quirks and oversites in design (Snake pokemon will "glide" over the ground instead of walking, walking is weird in some areas with the grid and free movement, battle sequences bombard you with text, cannot zoom in on map, poketch is a pain to use, etc)
Exp share, poketch, hidden moves, and PC box anywhere are welcome additions, though an exp share toggle would have been nice to silence the critics.
National Dex from Gen 1-4 is included, and megas, zmoves, and dynamax are not included (which I prefer).
