For each User Upgrade, it is possible to individually disable other upgrades. This is useful if you have multiple tiers of the same upgrade and only want users to be able to purchase one tier.
When would this be desirable?
All logged in members have access to all upgrade options, at least at this time. When would disabling the other User Upgrades be of use?
This is all I can think of:
- Selecting one of many sports teams to select to 'win' for the season. Have the upgrade enabled for purchase up until the start of the season. Then at the end of the season reward the people that picked the winning team somehow. Football, soccer, baseball, F1 racing, those types of things...
- Possibly a gaming Klan - though I know nothing about those, pick one, and only one, of many available.
