Great game
But the spellbook should be organized in categorizes like Mom/homm3, naturespells with green color around them on the nature spells page etc. They can be categorized by element, city, unit or battle spell maybe. This will make it easier to find the spells you need
If many of all the other great ideas on the forum will be implented in the fianl game, I am about to say, that you have made a great succesor to MoM. Nothing beats Mom, but you guys are on the path.
Now we just need someone to make Dungeonkeeper 3, then 2 of the greatest strategygames of all time have been renewed and I and lots of others would die happy
