Board Game Arena

I'd like to watch replays for specific games and player counts, is there a way to find such replays? I've looked for hours but can't find a way to search for e.g. Gaja Project Replays with 1 Player (Solomode)...

I'm looking for the same feature. This would be a valuable addition.

I don't believe you can. But here is two ways to get close to what you asked:

You write "gaia project" in the top left, are in this page https://boardgamearena.com/gamepanel?game=gaiaproject then "Number of games played: xxxx"
You will have all the game of that type.

Or if you have a specific player like yourself
You take your profile https://boardgamearena.com/player?id=90512110 then Vortilion's games history https://boardgamearena.com/gamestats?player=90512110 and you got lots of settings to see your own games.
