Personally, I think Harry's suggestion is a good one but needs to be time limited (a subscription) and not a one-off payment that lasts forever.
With the exception of tokens (which you can already purchase for real money), all of the benefits Harry lists are merely cosmetic so they won't make a team any faster, but it would add to the enjoyment of the game for many.
Why would people leave? What's wrong with allowing Managers to spend real money on premium liveries, customisable race suits and helmets and individual user selectable race numbers?
The money raised might allow IGP Manager to dedicate resources into resolving some of the long-standing bugs.
Regarding comparisons with EA Sports, are you talking about that huge and successful video game studio?
Might as well explain my points.
Yes, I am talking about the big studio "EA Sports" but what I will explain deeper is my reasoning for why managers might leave.
Most people (including myself) don't like to spend real world money on in-app purchases. I know it supports the developer but it's more or less a cash grab - no offense to the people at iGP Games.
I like this on the surface but the price is what makes me turn away - 10 to 25 dollars is too much for mostly cosmetics even if it does support the game.
