Custom fan made game. What makes it unique is that it is entirely open world - there is no main story and you're free to play however you want. It's almost like a Pokemon version of Skyrim. You can choose to start your adventure in either Pallet or New Bark Town. But from there, where you go is up to you. HM traps, plot-based roadblocks, and other obstructions have all been removed, leaving the whole map open for you to explore from the start. There's even a bridge added so you can travel straight from Johto to Kanto (or vice-versa). RTC on this cartridge is static. However, each time you start the game you are able to set the clock to change the time.
There is minor trainer customization (appearance and starting town) and you can tackle all 16 gyms in any order. Gym leaders' levels and team compositions will scale up based on the number of badges you have. After you've conquered them all, you can re-battle them at whatever 'badge scale' you wish, to take on their strongest or weakest teams. You need a total of 8 badges (any 8) to challenge the Elite Four.
All 251 Pokemon made obtainable
7 different male and female trainer sprites to choose from, with basic color customization
28 different selectable starter Pokemon
Restoration of Kanto dungeons (Safari Zone, Cerulean Cave, Seafoam Islands, etc.)
Following-Pokemon, and unique menu sprites for each Pokemon species
Running shoes, and fast-travel options
Dedicated NPC for trade-back evolution
Runs awesome and the cart looks really cool!
In the specific version of the game that this cartridge holds, it doesn't let you choose between Pallet Town or New Bark Town, it lets you choose to start in literally any town or city in the game. (For best start I recommend starting in Goldenrod as you can get two gift Pokémon there. Eevee at Bill's house, and Kenya the Spearow from the north checkpoint in Goldenrod. Both of which are shiny huntable.)
Super fast shipping awesome game!!!
The game is really fun and enjoyable to play, you're not limited to Starting at New Bark Town, or Pallet town, as you can actually choose any Town from either Jhoto or Kanto to start your adventure although If you choose a town with a higher difficulty to start from the Pokemon in the grass will be of higher levels.
