From what you said about math that is your only choice IMO ,since any decent college offering you a Computer Science degree will include lots of math compared to computer information systems degree.
Will computer information systems be of any use?
For example, I know of plenty of friends/co-workers that even got a masters in computer information systems with no more math than algebra.
I mention discrete math to them and they have no clue what I'm talking about sad but true.
My school required tons of calculus, discrete math, linear algebra,etc to get my Computer Science degree as most schools do. Those that couldn't handle i.e. pass the required math usually switched to computer information system,which included most web programmers since it didn't require any math at all.
I honestly don't see how you can do any serious game programming without as much math as you can take.
If you stick to web, business programming I can see how but even then a basic knowledge of discrete math should still be required and reinforce your programming since a ton of the data structures, algorithms can be traced right back to graph theory from discrete.
p.s. Also, I would try giving math another go especially with all the resources available today like Khan Academy, MIT and Standford Itunes University math courses covering everything you ever need. I know it would've made all my math courses a ton easier or it seems like it would've from what I've seen since my book/instructors weren't nearly as good at explaning things.
