I honestly hope that you guys arent finished with the game, because it still needs a little more work.
Dont get me wrong, its a good game right now in many aspects but it certaintly would not be the best game in this genre.
The main reason i say this is because the magic isnt fleshed out enough for there to be a war of magic, and sadly its suffering from the exact same thing that prevented age of wonders from being a worthy successor to master of magic, and unfortunately this game has even less spells than age of wonders.
So please spend some time and flesh out the spell books. Here are some examples of things that can be done.
1: Give each school more offensive spells, because unfortunately it seems that death and fire have the vast majority of offensive magic. These should include both tactical and strategic spells.
2. GLOBAL SPELLS : I cant harp on this enough, because frankly this is what made master of magic so great. Not only did they have very powerful global spells, but they also had a system of global sparring. Global spells, Disjunctions, Spell Stealing, Enchantments that struck an enemies cities with an earthquake whenever a spell from a specific school was cast etc...
3. More Summons are needed, not only do we need more summons but there should be high end summons that summon kickass monsters on the scale of a dragon. Also where are the undead? We have a whole school devoted to death but not one skeleton, zombie, vampire etc... Also each school needs summon spells. i.e. Angels for Life magic as an example.
4. Last but not least we need more spells that interract with the world map. We used to have raise/lower land, create mountain, destroy land, flood and Kurgen's volcano. I noticed that Kurgen's Volcano was put back last patch, but we are still missing flood, create mountain and destroy land. I would like to see these added back into the game. Also Age of Wonders had temporary barrier spells like Holy Forest, Unholy Forest, Poison Land etc.. that would act as temporary barriers. It would be nice if a group of these were added for each school.
Examples:
Life - Consecrate Ground - Blesses and heals all Life units that enter the area and Curses / Damages those that follow death.
Death - Desecrate Ground - Exact opposite of Consecrate.
Fire - Wall of fire - places a temporary 3x1 wall of fire that damages all units that pass through.
Air - Arcane Tempest - Calls down several tornadoes that throw units entering it in a random direction as well as damaging it.
Water - Torrential Rains - Floods a small area preventing any passage for a few turns.
Lastly It would be nice to have the option to play a game with the Dynasty system enabled, where Sovereign's can marry, have children etc.. and most importantly it would be nice to have a toggled option where you can kill Sovereign's and Heroes. Examples there should be a chance that Sovereigns and Heroes can die from battle wounds a certain percentage of the time and perhaps add in assassin units that can be used to assassinate Sovereign's or heroes.
