Then they could have tried this.
A 3 month promotion that is tabulated on the fourth for billing.
Client cost for fourth month of game play.
3 referrals = Free Month
2 referrals = $5
1 referral = $10
0 referrals = $15
In the first run of this promotion assuming that only 1/2 of the players would participate total from the original crop and we half that each time as interest wanes.
--------------------------------------------------------------
Original Crop(OC) = 4500 players
Month 1
OC Referred 1 new | 2250 * 15 = 33750
OC Referred 0 new | 2250 * 15 = 33750
Month 1 referrals | 2250 * 15 = 33750
Month 1 - Total Income = 101,250
Month 1 - 33,750 additional income
Month 1 - 6,750 total players
--------------------------------------------------------------
Month 2
OC referred 2 new 1125 * 15 = 16875

Month 3 - Total Income = 168,750
Month 3 - 101,250 additional income
Month 3 - 11,250 total players
--------------------------------------------------------------
Ignoring Expansion Here and just estimating billing...
Month 4
OC referred 3 new 562 * 0 = 0
OC referred 2 new 563 * 5 = 2815
OC referred 1 new 1125 * 10 = 11250
OC referred 0 new 2250 * 15 = 33750
Month 1 referrals referred 2 new 563 * 5 = 2815
Month 1 referrals referred 1 new 562 * 10 = 5620
Month 1 referrals referred 0 new 1125 * 15 = 16875
Month 2 referrals referred 1 new 1125 * 10 = 11250
Month 2 referrals referred 0 new 1125 * 15 = 16875
Month 3 referrals 2250 * 15 = 33750
Month 4 - Total Income = 135,000
Month 4 - 67,500 additional income
Month 4 - 11,250 total players
--------------------------------------------------------------
In 4 months this could result in... 540,000
Versus the original model of... 270,000
If the promotion were to end that month.
The fifth month, and sixth and seventh etc. until the promotion started again, would be...168,750 once the promotion has ended.
Add that to the results of the 4 months and you have $708,750 and you have completed less than half the year which would mean if you stopped there...
708,750 + (7 mos @ 168,750) = 1181250 + 708750 = 1,890,000 yearly
Month 5
OC 4500 * 15 = 67500
Month 1 referrals 2250 * 15 = 33750
Month 2 referrals 2250 * 15 = 33750
Month 3 referrals 2250 * 15 = 33750
Month 4 referrals not calculated as promotion has ended but that doesn't mean new players didn't arrive.
We increased the population and the monthly budget to keep regular updates going. Of course it is just an estimation but it's a plan that may have worked better than not changing the structure that they already knew wasn't working when the project were purchased. Hope I didn't make any calculation mistakes but that's an idea at least. I try to be a problem solver
