My brother and I have been mulling about a Pokemon fangame that is a bit of a rougelike.
You'd start out in a central city where you could choose your path between a variety of trails named after previous Pokemon games. Those trails having a substantial impact on which pokemon would appear along the way.
Each time you begin a trail run, you choose one of three starters as normal. These starters you can choose from correspond to the trail you've chosen.
Red Trail: Kanto Starters
Silver Trail: Johto Starters
Emerald Trail: Hoenn Starters
Pearl Trail: Sinnoh Starters
White Trail: Unova Starters
Lifetree Trail: Kalos Starters
Solar Trail: Alola Starters
Bulwark Trail: Galar Starters
These are not all the trails you can choose from. But this is just a taste of how you can explore the mysterious foggy Nazori region.
Every single Pokémon can be caught in this region, but not in a single run. And pokemon caught in a previous trail run cannot be used in future runs. Only in multiplayer battles or various battle facilities.
Can you catch 'em all?
(Should I make a Discord Server on this?)
