Thank you for your pledge and support tpostman67! Welcome to Theme Park Studio.
The pledge made on your credit card doesn't get taken out unless we meet our target goal. You make your pledge now on the Kickstarter page, If we do reach our goal amount, after the program closes next month and only then will your credit card be charged. No charges will be applied at all if we don't reach our goal.
The game officially releases on Sept. 15th. What Early Bird refers to is you will get your copy early, sometime before the public does, just like getting into Disneyland an hour early on their early bird special.
Please keep in mind that we are still developing TPS and haven't even started beta testing yet. You will get your Early Bird reward sometime after the conclusion of beta test but before actual public release.
Remember if you hurry and make a $50 pledge or more, you will be included in the TPS beta test program, but these beta test reward slots are filling up fast, so don't wait too long if you are interested in that.
