It's not really a good thing to promote competition, here is some comments I found on another site:
The latest game in the popular Majesty series, Warlock: Master of the Arcane introduces turned-based strategy and global conquest to the fantastic world of Ardania. In a time of chaotic upheaval, the player takes the role of a great mage, a warlord vying for ultimate power. Your mission is to build an empire, expand your borders, research new spells and conquer your enemies. Become the ultimate Warlock and rule over all of Ardania!
I just played the demo and was really surprised by it. Anyone disappointed by elemental war of magic should be pretty happy with this one. Basically if you like civ or better master of magic, you're probable gonna like this. The demo was a lot of fun but their is a turn limit, so your not gonna play a full game. I really recommend trying the demo, I've really heard nothing about this before so it's a real pleasant surprise.
I had a chance to try the demo and I was very impressed. The game is not too complex and it's easy to learn. The city development does not demand too much work, which give you the time to enjoy the other parts of the game. ( One of the problem in CIV, MOM and MOO is that 80% of the player's time is placed on city/colony construction).
Besides a few bugs, the first drawback is that magic seems pretty weak. I have have not check the whole spell book, but I am starting to get used to it. Everybody seems to be scared that wizards are too powerful, so they always dwarf them. The second drawback: it's not moddable . Well if you want to mod the game, people will have to hack it like in the good old times. That's a shame because it would have made a wonderful master magic mod.
Considering that the game is pretty cheap (20$), it might still worth the buy.
