Comparison of Rewards in Survival Modes

For ease of comparison, let’s ignore power-ups, units, energy packs, trophies, and—of course—the fun factor!  Let’s also ignore energy expenditure and experience gained.  Instead, let’s focus on Coins and ores earned.

Survival Modes 1.0 (First Strike) and 2.0 (Sky Assault) had the same rewards as far as Coins and ores went.  In either one, you received the following for completing one round of 60 waves:

Coins: 294,000

Oil: 11,760 (trade value of 235,200 Coins at 20 Coins per Oil)

Wood:  12,265 (trade value of 245,300 Coins at 20 Coins per Wood)

Ores:  6080 (trade value of 1,216,000 Coins at 200 Coins per ore)

Total trade value in Coins: 1,990,500

The exact mix of ores (gold, uranium, aluminum, copper, and iron) was relatively even but varied, depending on what ore type you produced yourself. 

For completing all 60 waves in Survival Mode 3.0, you receive a total of 1,026,500 Coins.  This is very close to just HALF of the total trade value in Coins of the earlier Survival Modes.

The next points in comparison would be the net energy expenditure, experience gained, and units lost (or not).  That is a more complicated analysis that I may or may not do in the future.
