Before starting the run I was considering: what is more likely: to do this map as any% or 100%. I thought there was nothing helping me to get to 50% of the cities fast enough - I didn't see the ruins on the map next to my capital - so I thought it'd have to be a 100% run. Turns out that I find 4 wizards in those ruins and decided any% it is. I was lucky that the wizards lived long enough to get me to 40 cities and to the win.
