In endless, a city's first district take 105 production. To Produce it you need to clear 5.25 forest tiles. Each tile take 8 turns with a scout.

In Blitz, first district cost 13 production, you need to clear 0.65 forst tiles. Each tile take 1 turn with a scout.

The time diffrence is normal, but poor endless players only get a 1/8 of the value of the same forst tile.

Adjust chopping value to gamespeed.
