I was one of poeple who preordered elemental war of magic before, and while not hating the game , i was overall disspointed , specially with ai that didnt challenge you.
Now i have played i think at least 6 hours of fallen enchantress and i think its a great game, what elemental should be, great stuff having it for free
For me ai on normal was challenging , lost first 4 games, now wining my fifth. So im really happy with this, will try further difficulties soon:).
Only thing i miss from elemental is what i remmber to be muchmore quests and more funny descriptions, but seems altarn kingdom gets the quests as bonus here.
