More information

New Pokémon
Let's start with the pokémon, which is one of the most interesting parts. We will have pokémon from the first generation to the fourth generation, but we will also have new pokémon, with many species exclusive to the voultan region.
Regarding movements and skills, we will have upgrades up to the fourth generationalthough most of them are from the third generation. We will have fairy type, as well as physical and special damage, with many bugs fixed. About the duration, we will have 8 gyms available, which currently have been updated.
Features and Graphics
Now let's move on to the most important features and functions, because there is quite a lot to tell. We will be able to travel between different regionsYou will meet new and old islands where you will meet new characters that will accompany you in the adventure.
Now I will comment on the graphics, as they are also quite good. If I have to say that the graphics are very gba style, but it is true that we have changes in exterior and interior graphics. The best thing is that we will be able to fight against new characters, like team rocket or new gym leaders.
History
Today is the date you have been waiting for a long time. This moment is really important for you and your journey to explore the world is beginning. A few months ago, you found out about an opening in the school of indigo plateau trainers in kantoAlthough his cv is not good enough to be accepted, but this also helps him to make another big decision and he decides to explore this region.
On your journey, you must train your pokémon and then challenge gym leaders to collect badges and finally meet elite fours.
