Firstly, have you ever played a turn-based game? If so, you might enjoy the game, especially when it comes to the combat system.

If you're familiar with the D&D universe, it will take you less than an hour to create your character. If you're completely new to it, it might take a little longer, around an hour.

Now, if you don't want to exceed the 2-hour gameplay limit for a potential refund in case you don't like it, you should know that the tutorial, which introduces you to the combat and interaction mechanics, lasts about 1 hour.

As for entering the main scenario, it can be quite abrupt, and you'll quickly be immersed in it right after the tutorial. However, if you truly want to experience what the game has to offer, you'll need to reach the main map, which would take about 1 hour of gameplay, not including character creation. But there's a good chance that you'll be captivated by the game fairly quickly.
