Pokémon HeartGold and SoulSilver

Pokémon HeartGold and SoulSilver are two games in the series of Pokémon RPG games. They are remakes of the second generation games and part of the fourth generation of Pokémon.

Why It Makes You Gotta Catch 'Em All in Johto, again

 * 1) Johto is recreated with the engine of Pokemon Platinum Version, so 3D graphics are featured in the overworld and the region has much more details. Some cities and special battles have new theme songs rather than just remasters.
 * 2) There a new area in the Johto Region which leads to a new Safari Zone, something that was missing in the Generation II version of the game.
 * 3) The first Pokémon in your party will follow you around in most areas of the game.
 * 4) The game comes bundled with a Tamagotchi like accessory that allows you to transfer a Pokémon in your Boxes to it.
 * 5) The revisit to Kanto is also improved so that it takes longer to complete than before. Also, the Pokémon League can be fought again after obtaining all 16 badges with higher levels.
 * 6) The final battle with Red is made more epic.
 * 7) After beating all 16 Gyms, going to Celadon Condominiums and talking to one of the Game Freak employees you will get an item called GB Sounds. Once activated, it replaces HeartGold and SoulSilver music with original Gold, Silver and Crystal 8-bit music.
 * 8) (SPOILER) The Arceus's Event in Sinjoh Ruins.

Bad Qualities

 * 1) The level curve from the original games is overall untouched, leading to excessive grinding for certain Gym Battles, and encountering trainers with hacked Pokémon, such as a Level 20 Slowbro (though Slowbro can be found at level 15 at Slowpoke Well's B2F) and level 50 Dragonite with illegal moves.
 * 2) Since the rocks and the "special magnetic field" from Sinnoh are absent in these games, Magnezone, Probopass, Leafeon, and Glaceon are unobtainable without trading.
 * 3) Wild Pokémon distribution is barely fixed, as certain Generation 2 Pokémon like Houndour are still only available in the post-game Kanto region.
 * 4) Once again there are some game events that were only available for a limited time, now they can only be played via hacking or glitching.
 * 5) You can't do the glitch that allows you to have all of the 3 starters Pokémon anymore.
 * 6) For those who played the female protagonist of Pokémon Crystal (Kris), in these remakes she is completely replaced by a new character named Lyra.
 * 7) For those who want to challenge Red again after beating him, the Elite Four must be defeated once again. After that, Red will reappear in Mt. Silver.
