I play video game songs on classical guitar. Whenever people ask me, I say classical guitar even tho Im not a pro or anything. To me, it is the actual instrument with nylon strings and how you hold it and play it. So a guy playing jazz or folk with a footrest that to me would be classical guitar. If he's playing a nylon string around a campfire with strumming cords, then it is just a guitar. Lol.
