  • Unexpected AI moves

    Okay on my first "Map"

    I was playing a game as the Celts and had a peninsula of the great pangeal world cornered off to myself and had set of a defensive line (the thick greay line). I had expected that if any of the AI civs were to attack that instead of going through the jungle they would just take the quick way on the road into my defenses as they usualy do from my experiences. But NO! My defenses proved to be exactly what they were modeled after, The Maginot line! One of the AI civs declred war and the other two (playing on a tiny map) fallowed suit. I thought to myself "HA! they will tremble before my power!" but instead in the next few turns they sent 50+ mounted units of various sorts around my wall, through the jungle and straight to my capital!! All the meanwhile I left my guards at the wall because I didnt want the enemy to take it, and in two turns my capital was bye bye, along with my king, and any hope of winning.

    I was beaten by the AI for only the third time in all of my civing experience! and all because I hung on to my old ways of war, well rest assured I promptly tossed my outdated startegies out the window (or so I had thought) and started a new game.

    This time I hade an entire island to myself, built it up all nice and purdy and then WAR! A civ half way across the this time standard world had declared war. "They dont know how to use boats, they'll never see the glory of death at my hands" Two turns later a galley pulls up off my shore (2nd map grey dot) I figured that if they had anything in the boat they would unload right onto the shore and attack the closet city, meeting thier quick and painful death. and if they had nothing they would simply skim my shores and then disappear into the distant fog. I saw them start heading north so I figured they were empty, but I was wrong they went straight for my least defended, most out of the way city I had and landed right next to it. Needless to say they were still helplessly crushed when they attempted to attack, but the idea that the AI actually "thought" before making an attack impressed me

    It only brought one boat? Hmmm. Usually the AI brings several nowadays, or at least several in quick succession.

            The AI is vicious with the Yamabushi unit in the Sengoku scenario. The minute you go to war, they will swarm through the mountain with them, and start tearing up roads and grabbing workers as fast as they can

              I can confirm Space05us AI observation in my current game. The AI sent four galleons with several Frigate escorts thirty squares north to an undefended point on my island.

              Thank goodness, my enslaved worker population, (thanks to the jav chuckers!) built a railroad so I could move troops to meet the "attack from the rear" strategy.

              It appears the AI will marshall troops for more coordinated attacks. Bringing enough power to the point of attack.

                I can confirm that I have also seen this happen. One of my biggest complaints about the AI's warmongering in earlier versions was that they never waited to build up 'stacks of doom' before attacking, and instead sent a contant stream of units in small groups to their death. It's great that the AI has been improved in this respect.

                  Cool. Funny story Space05!

                  One thing tho: how did the AI know which of your cities were most poorly defended? Is it spying or cheating?

                    Probably cheating, but this is largely unavoidable. At higher difficulty levels the AI must make up for its lack of intuition somehow.

                    BTW - what difficulty level were you playing on anyway?

                      Well, I mentioned this in another thread, but I'll post it again anyway since it generated no comments:

                      When attacking with a superior strength unit, the AI seems much more willing to risk an attack with a damaged attacker. I have seen Cavalry and even Longbowmen that are already down to one hitpoint attacking full strength units with a defense of 1 or 2. They used to run and hide if they had any damage.

                        press the 'print-scrn' (next to the F12 )button, then go a photoshop like program, choose new then press 'shift+insert' (next to backspace)

                          Pre Frigates and Galleons, the AI seem to prefer to stick to the old naval strategies of having lone caravels travelling around the map.

                          This may have to do with the escort/transport issue, where the AI is now very good at handling transports and escorts, but is still at a lost with the multipurpose vessels such as galleys.

                          Yes. This appears to be the case. I was faced with several large infantry stacks in a recent war. I hit them with artillery hoping to reduce their numbers.

                          while some of the injured units retreated, many pressed on. I suspect the AI now calculates strengh of its own forces relative to your forces in an area, and if it has strength, it won't give up that advantage by retreating all of its damanged units.

                          FYI, there is only one AI. Difficulty levels affect production, unit support and research bonuses. This may have an affect on AI behavior, but at the end of the day, the AI you face in chieftain is the same AI you face in sid.

                          As for the age old whine about AI cheating, when players can sufficiently prove they themselves don't use cheats such as releoads, prebuilds, or picky start locations, then I'll listen. Otherwise, it's just a lot of preaching. The CivIII AI is remarkably cheat free, compared to previous Civs and other games. The AI needs to see some things in the game since unlike us, it doesn't have abrain, nor does it play Civ3 with a mouse and a monitor. It sees the game differently.

                            the AI has always cheated and send troops to your weakest city. it can even be used to explot the AI, as they will walk into traps you set up.

                              Can you still make them wander around in circles?
