The ones that you have taken will be the base for further studies in linear algebra and discrete maths.
As a game programmer you would probably find useful to do:
- Linear Algebra ("equation of the line" stuff, matrices, vectors) - ESSENTIAL for 3D graphics, game physics.
- Discrete Mathematics (that's where permutations come from), useful for AI models, and generally a close area to programming.
+ And any other math you like, because being a competent programmer usually implies to be a "mathematically mature" person (that means, you have suffered through a lot of maths and you have altered your way of thinking)
+ a lot of programming/problem solving practice wouldn't hurt
