At the same time, as an artist, this kind of excites me. As opposed to sculpting out one character in a game, I can create the entire game world on my own.
People pay to see originality and imperfections in work. To see the talents and craft of someone else. This is a quote lifted from the Diamond Age book I keep using:
"Hand art demanded commitment from the artist. It could only be done once, and if you screwed it up, you had to live with the consequences."
Many famous artists these days are production lines, hiring students or taking no more than several minutes to throw paint at a canvas (e.g. Damien Hirst). They won't survive for long when presented next to originality like you will be able to offer and when their methods are exposed.
Definitely keep focusing on the positives and on the quality of your work. The market will have your back I am sure of it.
