I have really been getting that one-more-turn feeling. My thoughts are that it is really good.
However, it is also a platform to build on. Now they have a working engine we need to browbeat them to ensure that the next three or four expansions add lots and lots and lots of content.
The Expansions and Patches Requests
Spells - Wants more spells. 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 - So much 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?
