Sorry for the late replies. Been busy lately.
There is a chance that my basement will flood, but I'm going to take precautions against it.
First of all, in the spring I'm going to try to grade the area around my house as much as possible to keep rainwater from draining towards the house. If I can't get the proper grade, I have a drainage system planned out.
Once I get that done, I'm going to get my basement waterproofed. It's pretty expensive to get done, but It will be worth it in the long run.
I also kept everything away from the sewer drainage in the basement. To further keep the possibility of having a drainage backup damaging my games, I'm going to put up some drywall that will keep water away.
If all that fails, and my basement still floods, well that's what insurance is for!
