Play Pokemon Sienna (beta 3.1) Online
Pokémon Sienna throws you into that cozy GBA world you remember, then surprises you with oddball regional variants and gym battles that actually make you rethink your team. Feels like finding some hidden gem your buddy coded in their basement—rough around the edges, but full of heart.
Pokémon Sienna feels like someone dug up an unreleased GBA game and polished it just for fans. The pixel art nails that classic Pokémon vibe—you’ve got your usual tall grass, quirky towns, and trainers who just can’t wait to battle. But then you run into these weird little twists, like a new regional variant or a side quest that actually makes you stop and think for once.
I got stuck early on because one of the gym leaders has this bizarre team setup that wrecked my usual strategy. Had to backtrack and catch something completely different, which honestly felt refreshing. The beta’s got some rough edges (obviously), but the passion behind it shines through—like stumbling onto a secret ROM hack your friend made in high school, but way more polished.
If you miss the days of grinding levels on a dim GBA screen, this’ll hit the spot.
