Actually, if you can grab it at a discount price, the game worths the time invested. There are a few ways to skin a cat (to do a quest), and there are some consequences to your choices. But not too many. One interesting thing it's the fact that if you have the proper armor/uniform/costume, you can obtain quests that you wouldn't get otherwise. You will juggle with those costumes in many ways and you will get a perspective from every faction in the game. Don't expect good graphics. The graphics are functional and provide the environment, but it's nothing to write home about.
Overall, it's a good game, which had an incredible potential to become a great one. But you can't expect that a russian company would have the same amount of money or experience as an western company. And with those russians, you never know: they can come up with an incredible concept and deliver it in a flawed manner ( Precursors, comes to my mind ) or they'll make a rather well polished game like King's Bounty.
So if it's around 10$ or lower, grab Hard to be a God. The story unfolds once you advance deeper and deeper in the game. At the beginning you are in a fantasy world, fighting with medieval weaponry. Towards the second half, the science fiction part starts to unveil and you ill get a different feel (the older guys might remember Wizardry and Might and Magic which always had a science fiction component).
