Ignoramus: Age of Wonders is my favourite TBS game of all time, and another AOW game with a soundtrack by Michiel van den Bos seems extremely promising and all... but only six available races? No halflings, lizardmen or frostlings? No undead?!
Otherwise it looks pretty cool, and I hope they'll release an expansion pack with additional races, after the initial release.
There are less races mostly because of the customization. For example, you may have regular goblins, but you also can have angel goblins if you play as theocrat ;P
In short, less races, but you can customize them.
