In my 2nd year of college, quarter of the first semester, we had to make an 2D endless running game. This was the year right before we started to learn 3D modeling, instead we learned about 2 Danimations and spritesheets. Now this was also a time when I used Photoshop a lot; I hand drew all of these. So rather than exploring with Adobe Illustrator, I decided to stay in my comfort zone and spent a lot of time drawing each frame for the animation.
