Good Morning/Afternoon/Evening My fellow sound designers

I recently bought Reaktor 6 by Native Instruments. As i started to work my way through the manuals and a thought crept into my mind, “Is this all worth it.” Does learning more advance methods of sound design like Reaktor, Pure Data or Csound really add more value to your projects then just simple pitching , time stretching or long convoluted processing chains?

Side Question : I want to get into sound for games what game engine should I learn first? There are so many and I know nothing about game sound design.

Much Love
