This sounds awesome!
Can I request for a future season one more reward category? Reserve 5% to reward all players proportionately thusly:
Total resources accumulated (including spent and unspent) from all sources (including buildings, recycling, offensive fleet actions and any other sources) on all holdings (including colonies and main planets).
Then award a portion of that 5% in a distribution to all players from 1st place through X.
You can use the equation 1/2^n (where n is their ranking for resource accumulation) to determine what portion of this 5% goes to each ranking.
Sure, some players could probably figure out ways to game this for a higher ranking. I think don't worry about that, and make the reward small enough it's not worth it.
The reasoning for this added reward category is that, knowing I'm never going to be in the top 100 or hold a record, there's little reason for me to try a little harder to move from, say, position 3051 to 3011. But if it's the difference between $0.000145 to $0.000155, well, there's some acknowledgement that something happened and I can get myself to log in that one night I'd otherwise miss. I like those little financial nothings that still serve as mental boosts.
