HOMAM 3 is one of the games that will forever be in my heart. My friends and I have spend thousands of hours playing this game and also had fun with simple, yet great editor, which allows you to create your own maps and campaigns. For me, this installment is the best from the series - it's well balanced, you can play it with your friends using the hotseat feature and have endless hours of fun just like we did.
But beware! If you start playing this game, you will surely get in the HOMAM loop which can be summarized by the sentence "one more round and I'll go to bed".
No you won't :)
