Its pretty hard to mod especially when the game itself restricts you.
I once had an idea about a new ZH general called Advanced Weapons General. The idea looked good on paper until I knew how to mod. Most of the abilities I planned wasn't supported by the engine!!! Abilities like the tractor beam and the magnet tank were not supported. I hated modding after that. After some time I realized that you can still create a lot even with those restrictions so my interest in modding returned.
So here I am. A proud member of ModDB modding community.
