The only tips I like to give new players are:
- Quicksave fairly frequently: autosaves aren't very frequent and you can lose a lot of progress if you die
- Accept failure: failing a roll can lead to interesting results and give you a good story
- Don't over-think things: there is no one "correct" way to play this game. Just do what seems like a good idea at the time and enjoy your own game. There are things you'll miss in a single playthrough, but I can't imagine it's much fun trying to follow walkthroughs to make sure you've seen everything
If you haven't played D&D before there will be some things that you won't immediately understand, but plenty of people will be able to help out if you need it. Or just experiment - you can save in the middle of combat or a conversation if you want to see what happens. And if you want to look under the hood at the rolls, open up the combat log at the bottom right.
Above all, enjoy it!
