I think this game rocks!
It is a really good solid foundation. I already find it addictive like Civ. What I want to see now is a lot more content added in free patches and paid expansions.
Spells - MORE MORE MORE. Interesting global enchantments please. Armageddon anyone? Eternal Darkness? Season of Light? Chaos Channels? Global Fertility? Battlefield spells - Prayer, Darkness, Mass Confusion, Rain of Fire etc. etc. The devs should basically rob the MoM, Dominions 3 and AoW 2 spellbooks.
Artefacts and Equipment - MORE. And more interesting swords, rings and amulets than just +1 - +5 please?
Equipment Abilities - To give more special ability options for regular troops? Bandage pack to give healing power - training component to give First Strike etc. etc.
Building Art Content - MORE and varied building components for the mod section (crystal buildings, spires like in AoW 1 & 2 for the elves, rounded domes and organic buildings like WarCraft 1 Orcs and organic structures like Zerg or something)
Creatures - Wants more monsters (not just humanoids).
Races - Non humanoid, maybe different gameplay mechanics?
