Ok wait edited:
I was like WTF you guys talking about.
I meant: Might and Magic: Heroes Kingdoms
Appears HOMM online is a totally different game.
This other game Kingdoms is run by Ubi, and is free, and has no client installation. Its a browser game. Create an account and each account gets 2 servers.
Wayyyy better than Ultima Online
Heroes customization is pretty big. You hire from a tavern. There are attack, defense, and magic traits. But each hero has different limits like 60/60/0 or 30/60/30 basically they all equal 120. Also each hero gains their stats differently. Some start slow but then go fast after level 10 or some are opposite.
I think there are 12 classes to choose from, and each hero can speacilize in 3 classes. And from each class it breaks down into another 4 speacilities.
There are resource seasons, where sometimes resources are cheaper or more expensive to sell on the market.
Pillaging, sieging, spying. Hurray.
