Heartgold and Soulsilver are great Pokémon games, unfortunately stuck in the shadow of Kanto. Johto does many things better than Kanto. The story is slightly improved with cute little quests, the art style is charming, your first slot Pokémon follows you around, and there are a ton of little quirks that build out this game. It's only real issue is that Gen 1 Pokémon are so much more prioritized than Gen 2. So many routes are exclusively Kanto mon, half of the gym leaders use no Johto Pokémon, some great Johto mon are locked to the post-game in Kanto. It's really unfortunate because Johto has some really amazing Pokémon designs that just don't get to shine here. That being said it's a serviceable sequel to Kanto, although I wish it had it's own identity in terms of Pokémon variety. Raikou, Entei and Suicune are a cool change up from the legendary birds which stuck to one location. The time system makes for a nice environment when playing at certain times of day but didn't impact Pokémon spawning enough to make it very in depth. Sunset is particularly beautiful when surfing. The music is amazing as always. A little thing is that the opening cutscene is one of my favorites. Despite my complaint, out of any Pokémon game this is the one I have revisited the most, Johto is a classic.
