Steam or Standalone?
There are a few differences between the Steam and Standalone versions.
- No need to create an Altitude account as it authenticates through Steam.
- 52 Steam Achievements can be unlocked.
- Not bundled with Server Launcher or Server Configurator (only needed if you will host your own servers).
- You create an Altitude account after installing. You can switch between different accounts if you create more than one.
- Bundled with Server Launcher & Server Configurator
Be aware any Steam accounts can only be used through Steam and standalone accounts can’t be converted to Steam accounts. A lot of players have multiple accounts, but you do have to level up to unlock planes on each account.
If you play ranked PlaneBall you can link your accounts together so that your rating is shared amongst multiple accounts.
