I was wondering if it is possible to make a game with only computers and watch it. I know its a weird question, but I want to see the things that the hardest level of computer does and maybe learn from it (the game's battles also look awesome in the highest settings and I wanted to watch a good fight because I always lose rapidly). Thanks!
You probably won't be able to learn much from watching the AI other than how the AI thinks. The only thing you might learn is that the AI is incompetent. (Sins AI isn't bad as far as AI goes, but it cannot use strategy or tactics the way a human player would.) It would make more sense to watch replays of humans v. humans games, which are played over Ironclad Online. There might be some replays available somewhere. (The big problem is that people post them and then the game gets patched but older replays won't work with new patches.)
I just uploaded a 4v4 that I played last night as "Dark Vortex". 6 of the 8 players in this game are very experienced. So, watch the players Efejao (fighting flank), Dark Vortex (safe economy slot), Vojtisek (safe economy slot), Serak Warriors (fighting flank), Android (fighting flank), and Aquia (economy slot). In this particular map, each team started together instead of being intermixed with the opposition, so two players on each team were "eco slots" and two on each team had fighting slots.
You can only watch this if you have the most updated version of Diplomacy. (I just uploaded this for you.)
That file is ready to watch but you have to move it to the right place first. You need to put it in a folder called "Multiplayer-Record" which you can find in your Sins Application Data Folder.
