The Settlers - Mission 1 (Amiga) speedrun 19:41
73One would assume the DOS version to be faster than Amiga, but actually these might be relatively closely comparable. Timing Amiga version from placing the castle to screen freezing after victory conditions are met.
Trying out the strats discovered by tz, working just fine also on Amiga version. It's not necessary to capture the castle to win, dominating CPU in statistics is sufficient. It's probably not necessary to grab additional land or construct many buildings to increase stats. Key element is likely for CPU to construct at least one barracks quickly, attacking it immediately and hoping for a quick win. Still worth testing different ideas, not 100% sure yet on the exact victory conditions. I didn't capture the second barracks in this video, but the victory condition was met before the final kill, possibly calculated before animating combat results. I was a bit slow stopping the timer at the end, but this is about three and a half minutes faster compared to my DOS time.
