I would not recommend a graphic design degree if you want a job in games, unless you want to work for a publisher creating promotional material.

Look for a degree in animation, media design, multimedia arts, which are basically different names for the same thing.

Drawing is going to be a helpful skill to learn in any case, though you wouldn't have to be really great at it to be a graphic designer, where your job is to put together various visual elements, such as shape, text, photographs and illustrations in appealing ways.

3D is often compared more to sculpting than drawing, so you might get away with you lack of drawing skills.

A good art school will make you take drawing lessons no matter which major you choose, and by forcing you to work on these skills it is inevitable you will learn and improve.

At the end of the day, your portfolio, networking skills and attitude will take you further than a fancy piece of paper a school's name on it, and no one will ask for your grades.

These games use a technique called rotoscoping, which is animating over live footage.

Since you can use different styles of animation for this, results may vary, but it's a good place to start.

Unless you have an old school vector display, all vectors are eventually going to be rendered as raster.

Vector based graphics are infinitely scalable, so even though the final output will be rendered as raster, it will be easier maintaining the same crisp look independent of resolution. They tend to be smaller files when compared to raster graphics.

On the other hand, vector graphics have a certain look to them, which may not be appropriate for all applications.

Community Colleges are usually cheaper than private art schools or public universities, even when looking at the higher international student fees.

Where you choose to go makes a big difference too. Everything will be more expensive in California or New York, but you will have a harder time networking with professionals in the field which can hurt you when you are job hunting (which I assume is one of the reasons you want to study in North America.)
