The following is a changelog of differences from Fallen Enchantress to Fallen Enchantress: Legendary Heroes. It doesn't include a wide array of performance improvements (Intel was nice enough to come onsite and do some profiling on LH with our developers and turn out some good results); but it should give an indication of the tweaks and additions the game contains.
Swarm- All melee units get a bonus to accuracy and damage for every ally that surrounds the enemy they are attacking.
Fame- Clearing lairs, completing quests and building some improvements gains Fame for your faction. When enough Fame is earned champions will offer their services to you. Two champions are always offered and the player can only select one.
Champion level up system. Champion now have access to a trait tree that they can pick from when they level up.
Produce resources in your cities. Instead of constructing improvements and training units you can set your cities to produce additional wealth, research, growth or mana.
Huge Map type. Our biggest map size yet.
Steam Integration- Cloud saves of games, lots of new steam achievements and automatic patching.
City Count Penalty- You now get an Unrest penalty in all of your cities based on the number of cities in your empire (the more cities, the more unrest). This makes Unrest a bigger issue for larger empires and helps equalize the production and research of large empires vs small empires.
Food Growth Bonus- Cities with access to more unused food get a growth bonus. This way high Grain cities can not only grow to a larger size, they will get there faster than low grain cities.
Lots of new tactical arenas. In general enemy armies start a lot closer to each other so the battle can start immediately (and ranged units are in immediate trouble if you don't bring units to defend them).
Added a Production Pace slider to the game setup options. Player can now modify the research pace and the production pace seperately.
The World Difficulty slider now effects the level of monster in the world. Set it down to have monsters start out at a lower level than normal, or up to have them start out higher.
Each faction has a special ability
Altarian- Rush ability allows them to use their attack to go again
Ironeer- Guarded Strike ability allows the unit to attack for half damage but puts the unit into a defending stance
