I really like Affinity Photo, or better said, I really want to like it, but the Pen Tool for me is anything but frustrating. I don't know how to put this into words so I'm going to give the example of "How I would do this if I'm using PS".
Problem: I can't trace a line.
Photoshop Solution: Choose Pen tool -> Click the 2 points you want to trace -> Switch to Brush Tool -> Choose the brush you want to use -> Hit Enter Key -> Line was created.
Question: How can I do this in Affinity Photo? Why I feel is so counter-intuitive?
Thank you beforehand.

Affinity Designer is vector biased with raster capabilities.
Affinity Photo is raster biased with vector capabilities.
There are things each app can do that the other cannot such as, Affinity Photo can perspective and mesh warp, Affinity Designer has transparency gradients etc.

Neither is better. Each is more appropriate for some things than for others. Which will make it easier for you depends on the details of your specific projects and the workflow that you intend to use, and (probably) the requirements of the gaming platform you plan to design for.
But in general, I would say if you're going to be working with photographs and photography, use Photo. If you're going to be doing something else, use Designer. But you may also find some tools that are only part of Photo will be useful to you, so you may find that you'll need both to accomplish some tasks.
