Total War™: ATTILA - Assembly Kit Trailer

In recent weeks of working on Hyrule: Total War, I've been hitting hard coded limits and other barriers that for lack of a better phrase have limited many of my ideas. Someone else recently brought up the notion of porting to a more modern engine such as Rome 2: Total War. While Rome 2 seems to lack many modding tools and features, as well as amazing 3rd party tools that Medieval 2 has, apparently after doing some research Attila: Total War has a very powerful modding tool that blows everything out of the water: https://www.youtube.com/watch?v=gci9nYvto3s Most of the extreme tedium required to get all of my models and animations in Medieval 2 seems to be streamlined and made easy in Attila. There are several drawbacks with Attila at the moment though: currently there is no way to insert custom sound effects and music (practically a sin for anything Zelda related) and there is no way to create the Freeform Campaign that is the most popular feature of Hyrule: Total War. Ultimately though, it's up to the people who support and play my game as to what I should do. Should I stay with Medieval 2, or upgrade to Attila? Advantages to porting: - No more hardcoded limits. - Every NPC race I've had planned can be included. - No more 500 unit type limit. - Heroes can actually gain levels and abilities, complete with skill trees. - Engine can handle my high poly models better (which means more of them on screen at once.) The lighting in the engine is also much more dynamic, everything just looks better. - Civilians! Disadvantages: - I'd probably have to halt all progress on Hyrule Historia as I learn the tools and the engine to port everything over from Medieval 2. Seeing as quite a few people are constantly asking when the next level will be done, it's a fair enough concern to bring up. - No tools to create a Freeform Campaign. Perhaps if we work together we can convince Creative Assembly to incorporate such a feature, or create a 3rd part tool such as the one Medieval 2 uses? - No way to get any custom sound effects or music in at all. This is the main issue deterring me. Music is of massive importance to the mood and tone of everything in my game, I would never be happy not having Zelda melodies in it.
