Is 3DSMax required for modding CNC3?

I do NOT need to change art, modeling, animation, rendering, audio, world, maps, etc... nor do I need to create new entities etc...

I just wish to make mod changing some parameters of the games such as costs, buildtimes, countdowns, radius, damage, reloads, etc... that sort of things... like several mods I have seen kind of like Tactix etc...

Would I need to purchase that expensive tool from AutoDesk? I just wish to do personal research I can not justify that kind of expense...

Would anyone have any insight about this?
Thanks.

You only need 3DSMax if you want to do graphical work. For what you're describing, all you need is the Mod SDK.
