Only thing I will say is, Blender Guru's tutorial stuff is typically for rendering use, not game use, especially with his hard-on for subsurf and smooth bevels. Just keep that in mind as you further your learning of the software. Still similar workflows, just different approaches needed at times to handle X cases so you aren't added an excessive number of polygons in the process.

For example, a doughnut for ingame, sprinkles would be baked as a normal map and just pasted on top of the icing, and the icing would just be physically part of the doughnut model vs. a solidified mesh sitting on top.
