Still great, even after so many years.
Even if this game is really old, I'd recommend trying it.
It's good, when not excellent, in all of its aspects.
Gameplay is fine, though a little easy sometimes.
While melee foes can be defeated easily - hit and run (or run and hit, if you're a mage)- it sometimes becomes quite difficult to clear some areas with nearly 50 or more enemies attacking you.
Items that you get through the game are extremely helpful. In my opinion, too much - one of them can make you totally invulnerable for a short time. Just using a few of them for the end makes the boss fight just too easy.
With a higher difficulty, your enemies become faster and more numerous, and are more likely to deliver heavy, damaging blows.
The three classes are well balanced. With the fighter, you'll be quite strong even since the beginning, you can take down enemies quickly in close range, and suffer a little less from their hits.
The mage is the opposite: weak when in tight rooms and little space to move in; though, the ability to instantly strike from afar without any mana drain comes really in handy.
The cleric is somewhat in the middle. It's the hardest class to begin with, due to lack of range and massive damage; but then, when more weapons are available, things are compensated. Particular is the "serpent staff", the first weapon you get after the mace you start with. It allows you to make a vampiric attack in close range, restoring a little of your health.
Graphics are no doubt outdated, but they still suffice to give you the satisfaction of crushing an enemy with your hammer and seeing it explode, in a burst of gore and flesh.
Nearly all environments (made in a rough 3D) are well made and really fit the game.
Sound is the strongest point of this game. Music tracks are excellent, they perfectly match with the various environments and set you in the mood.
Grunts from your enemies and ambient sounds also fit the dark set of the game.
In conclusion, try it if you have chance to.
