Play Pokemon Sienna (beta 4) Online
You pick oddball starters, battle trainers who actually strategize, and explore a new region that feels nostalgic but full of surprises—like finding a lost GBA cartridge that never existed.

Pokemon Sienna (beta 4) is a fan-made Game Boy Advance title, released independently online. It exists as a digital artifact from an era when passionate creators began expanding on classic formulas, offering a new adventure built on familiar hardware. The game was developed by a small team, though specific names aren't widely publicized; it feels like a personal project shared with the community.
You control a young trainer starting a journey across the Sienna region, tasked with collecting eight gym badges and challenging the Pokemon League. The game introduces a roster of unique starter Pokemon, diverging from the traditional choices, and features trainers who employ more strategic battle tactics, often requiring you to rethink your own team composition. Exploration is rewarded with hidden areas and optional events, making the world feel dense and worth revisiting. The pacing is deliberate, with a moderate difficulty curve that respects your time without holding your hand. It feels like uncovering a thoughtful, handcrafted extension of the games you grew up with.
