Balance - Engineers +1 hammer
Economy - Increased city wealth setting to 25%
Strategic View - Crash fix for units rendering in background.
Thank god for that. The multiplayer game with my friend kept crashing when I tried to go into strategic view for more than 30 seconds, but without it ran like crap on my laptop.
And it's nice to see the engineers being halfway decent now. +1 hammer for one engineer? A farm on a plain was worth that much hammers. The only reason to consider these bastards was if you wanted a great engineer, and maybe if you had multiple specialist upgrades (Statue of liberty, + science per specialist + half unhappyness and food per specialist, though even then more scientists was better)
And the generate wealth option is now at least something else than a colossal waste of time. 10% of production to wealth is completely worthless. Most players had figured out that you were better off building scouts, workers or workboats and immediately disbanding them for the cash disband reward. This actually gave more gold per production than generate wealth.
