It's fun! It's easy to get frustrated and lost. I got a lot of help from looking up guides, playing through the tutorials and the tutorial campaigns, and testing out ideas on a blank map with infinite money.
Whenever I felt stuck, I would start over and apply the lessons I learned. That helped me keep going.
