Is there a recommended limit to not exceed with the number of variables (and let's include switches as well) in your game? I've once read a user comment on someone else's game having 100+ variables as inefficient. I've been trying to be efficient with the number I use, but should I really try? 30 variables vs 300 variables for example. Would there be any difference in performance? EDIT: Bonus question. Say I create 200 variables, but variables 100-130 are unused... can there be any impact on performance? Are those empty slots taking up any memory?
