Game design

For game designing, you can pursue animation and VFX. I think for game designing, Arena animation is the best academy.
For game developing, you can check Maya academy. Both are best, but note that designing and development are different field of gaming industry.

You may learn game designing for free from eDX or Udemy.

This has nothing to do with being a girl or a boy. You must be good at animation tools, imagination, and some high level programming as this is a part of this course.

Friend, Gaming is a less touched area hence interest and expertise can do great good in no time. Other than that, cloud computing and architecture is a great choice looking at the trend today. Prefer web after cloud computing. Computer science is a skill and hence don't worry about college and other things. Just get any best college you get and go ahead. Most of them have nothing to give other than degree.
