Can you add an option to surrend the game? Sometimes it is obvious you can not win anymore but the game drags on for +30 minutes.
So that one can just tank the mmr loss without karma penalty and proceed with having fun in an other game.

You can, in 2-player games, once progression passes 50%.

Maybe his / her suggestion is that this progression threshold be lowered? Or also to add this feature in 3/4/5p? (Of course everyone would have to vote yes to surrender to the winner). Best wishes.

Those are general BGA restrictions, it's unlikely they'd be changed (even if possible) for this game only.

The 50% threshold in 2-player games is intended to prevent abuse and cheating.
The fact that you can't concede in multiplayer games is because removing a player mid-game is usually a big change to the gameflow and there's no way you can determine (in general) what the final should will be. Even if all players but one decide to concede, that doesn't define the ranking among the losing players.

Thanks for sharing the useful information. Best wishes.

The issue with 50% progression is that it's not actually representative of half the game at 2p, because the progression only measures parameter increases. 2P heavily favours the engine strategy, which means players are unlikely to push the parameters until the late game. So you play games that don't reach 50% until generation 8 or 9.
