Heretic

The Good
Its Doom in a fantasy universe!! This is the first of the so-called "Doom Clones" I've played that I thought came very close to mimmicking Doom's feel when it comes to running around slaughtering hordes of monsters. I guess that given the engine this shouldn't be surprising. I thought the inventory and the ability to look up and down and to fly added a LOT to the genre. Some of the powerups like the Morph Ovum (a.k.a. the Chikennator) were very inventive. The Tome of Power, being much more than a simple damage amplifier, effectively DOUBLES the number of weapons!

The level design was also a step up from most FPS's of the time. Where other games would send you into military base after military base after prison after millitary base, Heretic had castles, cathedrals, towns, and caves. The music is pretty good, by MIDI standards, and provides the perfect mood for the game.

I personally really liked the graphics. I think the complaints some people have in this area stem from the fact that the Doom engine wasn't made specifically for large open spaces, and Heretic has a lot more of these the Doom.

The Bad
This was before mouse-look, so in order too look up and down you had to use the keyboard. The un-powered weapons bear an uncanny resemblence, in use if not in look, to Doom's arsenal. Eventually the game becomes repetitive, especially by the fourth and fifth episode where no new monsters, weapons, or items are introduced.

The Bottom Line
If you like Doom, you'll like Heretic. If you like Doom and are a fantasy buff, you owe it to yourself to get this game.
