Quoted from Aurich:

You didn't. Let's pretend that this kit is actually $100 cheaper (we don't know yet) and that it's technically equal to ColorDMD (that's not actually clear) you also paid for someone (with experience!) to hand colorize every frame of your game. Test it publicly, fix any bugs or issues, and basically release a solid, polished product.
With this kit you have to either do all that work yourself, or hope someone else does it (and does a good job), and there's a viable way to distribute that colorization that's not going to run into legal trouble (curious about that part myself). I'd also say it's pretty unlikely anyone is rushing to colorize LOTR since it's been done already.
So even assuming all the money and technical stuff is as stated, you're still in a good position. No money wasted. Enjoy your game.
