Not exactly. I’m assuming since I haven’t bought the game yet, but the trial is just that, a trial. A lot of the features and database libraries you will need for development projects are included in the main purchase. I’m pretty sure they lock down many of the features (extensively tuning the car, etc) in the trial version, and they will code it slightly differently from the main release. So if you like it, you will probably need to buy the full version. But the full version will be worth it, because the mod community will be expanding it to the point where you may not need another racing sim for a very long time.
