lila-openingexplorer VS FishNet

https://github.com/lichess-org/lila-openingexplorer (a database with stats for billions of chess opening positions)

Lichess' opening explorer looks like it's open source and can return an opening name from a given position: https://github.com/lichess-org/lila-openingexplorer

Final touches for lila-openingexplorer, a new chess opening database for lichess.org. Uses axum and rocksdb.

Here is the open issue on Github of it https://github.com/niklasf/lila-openingexplorer/issues/63

2) Rewrite it in Unity and use something like Photon or FishNet: https://www.photonengine.com/fusion https://github.com/FirstGearGames/FishNet

Which brings me to the next thing... If you ever want to jump between release all past versions and pre-releases are found here https://github.com/FirstGearGames/FishNet/releases

But he recommends https://github.com/FirstGearGames/FishNet

Crossfades are a little tricky. You're welcome to see how I do it in my networking solution https://github.com/FirstGearGames/FishNet/blob/main/Assets/FishNet/Runtime/Generated/Component/NetworkAnimator/NetworkAnimator.cs

Use Mirror, or the new Fish-Net solution.

I've been a bit "Unity offline", and even more so when it comes to networking solutions, because of my real job :), but LiteNetLib is quite good. There's also a new HLAPI solution called FishNet which seems very interesting.

Unity has a horrible history of f'ing up their network solutions, so I have no high hopes for it. Just because of that, I would go for Mirror (or maybe FishNet, which looks very promising, but I haven't had time to test yet).
