I am currently in the early design stages of a first person survival horror game called St. Abraham. I haven't started programming yet because I haven't been able to find a program that suits me. I don't have much programming knowledge (my dad does), and I only have 40-50 dollars to spend if necessary.
The program I'm currently looking at is FPS Creator, but it seems awfully limited in terms of entities and environments. Can anyone suggest to me a good program for making first person shooters?
