I know this is a silly question, But....

[E_Man]

I have a start screen with "Start" and "Tutorial".
If the trial account presses "Start" they go to a "Buy a Gold Membership before you can play!" level.
If they play the tutorial,
They can play quests, and at the end,
Gold Accounts win a weapon.
But Trial accounts do not.
Upon ending quests, Gold accounts gain access to 5 more levels including buildings.
Trial account however, Do not.

What is this tutorial mode? I never got this, I just had the options of either start, become a member, and options.
