With the current gold values, it costs 2.5 gold per troop per day. (2.5)
Assuming said person works in a moderate city: 40 Gold per hour
Plays CRPG with a 2X(the average) over 8 hours: 480 gold(approx) over the 8 hour play time.( 1g per tick, times 60, times 8)
That means you make per day: 1440 Gold per day.(40X24 +480)
Maximum army size attainable: 576(1440/2.5)
FIXED. That's an alright troop number
Assuming Clan has 100 memembers
Assume half play crpg per day: 480 x 50 =24,000
Assume 75 members of clan work: 40x24x75 = 72000
Total gold in one day: 96000
Maximum army size attainable: 38,400
That's actually pretty good.
