FTG Writes: DigiPen Institute of Technology is a talent pool for future game designers. Narbacular Drop, a student project from the college, eventually became Valve’s Portal. Tag: The Power of Paint, another project from the same school, was the basis for the paint in Portal 2. So if you want to see what Portal 3 will be like, check out Perspective. Like the other DigiPen projects before it, Perspective has a fantastic central mechanic. Portal jokes aside, it’s a solid game.
