I did a little googling and found this list of colleges with varsity esports programs:
I suspect that gaming is a negative for many older people and for many majors, but it can be portrayed as a net positive for other majors.
However your grades are going to bite you. If you had achieved top .1% rank while keeping your GPA at stellar levels, the colleges would be more likely to believe that you would be able to succeed at their institutions while keeping up your gaming.
Are your grades just uniformly B’s, or do you get A’s in math and science and C’s and D’s in humanities classes where you just don’t have the same raw ability? You can spin that sort of distribution more easily than you can spin getting poor grades because you just don’t care.
There are several threads on this website about students with 3.0-3.4 GPA who have had success with admissions (and even some merit money). You’re not getting into a top 10 school with your grades, you probably knew that, but there are plenty of schools out there who will look at you as a catch.
