Sure it's a God of War clone, but it has it's own merits.
The game play will feel immediatley familiar to GOW veterans. While you don't have multiple weapons to choose between, you do have your main weapon, a cross projectile (a la Castlevania), and different magic spells (which really don't play a huge part in the game). You can level up either light, or dark, attacks. Dark focusing more on magic and strong attacks. Light focusing more on light attacks and your cross projectile. The combat itself doesn't seem as impactful as GOW, mainly because of the camera angles used.
Which brings me to the more frustrating part of the game. Camera angles used often impact the experience in a bad way. While combat doesn't really suffer per say, it does hamper what you can see around the levels and makes the game feel much more confined (even though the camera is usually pretty zoomed out during combat sequences). Puzzles are often too easy and seem to be put in as an after thought or simply to be able to check off that they put puzzles in the game. Some objectives are placed around difficult jumps that often lead to you dying repeatedly only to replay having to get back to where you died.
Aside from those issues the game isn't really that bad. And the issues noted above don't really hamper the games progression as much as being a little hiccup. The biggest issue that they provide is that they don't make the game worth the original $60 it was charged for. But as I said earlier, $30 seems like more than a fair price.
What really stands out for Dante's Inferno are the levels. Level design are not very intricate, often a simple point a to point b affair. But running and fighting through the 7 layers of Hell is quite interesting. Often this is what really pushes you through the game and the use of The Inferno is not misused. Characters from the book (and history) often make appearences and you can either absolve or punish them for their sins. This simply adds another layer of detail to the game and helps to round of the package considering the lack of production in other places.
The Good - Hell is an interesting place to play in
The Bad - straight forward level design, odd camera angles, poor objective placement
The Ugly - Gore and Nudity seem over the top for the game. While it is Hell you wonder how much of it was really necessary.
