Only AI Training works in mist parts very well, but not 1v1 games versus the player, since players often want to play a game less than 2 hours : ) Top Quote

If i understand correctly, on each start of a game some random values are applied to the AI and the the AI files are Tribe specific. So on an 8 players map with 8 AI players of the same tribe all players uses the same AI configuration? That would at least explain why in the first test game all AI behaves the same (do not expand). Is there something like a rule of thumb what effect AI training has? Or vice versa: A rule of thumb what maybe a failure of the AI code may is?

A rule of thumb is hard to define as the performance is very map dependent. Especially the Empire is at risk to get stalled if no rocks and no stones mnining ressource is in the vicinity of the starting point. vicinity means start radius plus one small military building at max. So every reproducable dumb or wrong behaviour of the AI is most like a code error. AI Performance (in terms of how fast it can establish and extent a full economy or getting stuck) is most likely training dependent but needs to take map design into account. A good map to see AI most likely getting stuck with empire is Lesser Ring for example as marble is far on this map. Top Quote

So I think this might have been a hickup in the AI which will not be traceable at all. A replay might help to understand the issue but does not guarantee anything. Top Quote

But would it be helpful to post a save game or something? For example, check out this screenshot from a game I was playing today. Two of the AI players seemed to be fine, but this one seemed to be confused about something. Attachment: Top Quote
