You get the packs, the rest is just hooey...
You'll have to upgrade at some point, but it doesn't do anything at all; same as above - just cosmetic...
Very important, this one. Since you're dealing with little margins all over the place, you won't want to miss this: Always go for a sell-out rather than the maximum possible income here since it'll give you the few extra % in possession which in turn increases your chance of winning.
Ought to be one of your first builds/upgrades.
When planning the upgrades, try to make sure not to waste any days without building anything. Also try to schedule the upgrades so that you won't interrupt 'pay-out' cycles, i.e. start the upgrade of the medical facilities on the day you receive red packs, training facilities on the day you receive green packs, youth on the day you receive youth players, and you're good to go![]()
