"Similar, but better than Diablo II"
This game is very much like the Diablo games. If you are a fan of hack/slash games, you will love this. I feel that the action is just as good, the graphics are much better and to build a solid character, you need to do some thinking since the equipment options are great, so it's hard to judge which items are better than other (as some increase defense, some increase attack, so which way do you want to go ?).

The story is OK, honestly I don't pay too much attention to it. Multiplayer is fun and smooth and the higher difficulties are very challenging.

"Just O.K."
I found this game too be a bite boring. Graphics where fine not great, game play a bite boring, story I like and the Greek history information interesting. Still for the price it was wroth getting to kill time.

Reason for a bite boring is you cannot save when you want and then load it from that point. It saves but loads game to a set point(which is the last fountian you had active).

"A tide-over to Diablo 3"
Diablo and Diablo 2 standardized the formula for top-down RPGs: You hit stuff, you pick up shinies, you level, you find more shinies while exploring more darkness and killing demonic enemies.

Titan Quest builds on that with a unique class system, ragdolls/dismemberment , very rigid graphics (but by no means the best of the best, so it will run on some slower machines).

I'll make this short...You want Diablo 3, very likely. This will tide you over, if you don't want to revisit Diablo 2 for the tenth time over (but it's an enjoyable tenth time!) -- It has class, though it is linear, and the story is relatively boring - the items are great, visual, and have an appeal like that of the areas you explore...Egyptian/Roman mostly.

The class system allows you to mix two completely different (or similar) archetypes with eachother, say, a rogue with a ranger, or a druidic nature-caster with a barbaric melee class. There are alot of possibilities, some better than others, but all manageable. It's always relatively easy to gear up whichever "spec" you choose, but casters have a harder time. Best of all, if you are unhappy with your "spec" and you made it far, and don't want to scrap the character, there are programs and mods to reverse your selection, like like a respec in World of Warcraft.

The game feels like a very long run down a maze, and there are no randomized dungeons, so the replay is a little stale, but it's always fun to play a new hybrid class.

I recommend picking it up and trying it if you've spent a large amount of time with Diablo-like games, but if you don't enjoy hack'n'slash, it may not be for you.

"For those who want to play Diablo, without playing Diablo 1 or 2."
Do you find it unfair to rate a game a 1 just because your computer failed to run it? I do. So disregard the 1 star ratings. Now is this game any good. Let's get one thing straight; if you loved the Diablo series you WILL love this game. Ok that part is out of the way. This game offers 8 character masteries, but they shouldn't be considered classes. reason being that at lvl 2 you choose one of eight masteries and at level 8 you choose another one of the 7 remaing masteries. These two masteries together decide you class. This little addition to this game makes the replay value extremelty high.

There are three difficulties just like in Diablo 2. You have to play and beat the game on normal in order to unlock epic difficulty and then do the same to unlock the hardest diffilculty. You keep all your items and level when you move to the next difficulty. If you create a new character you have to start from the easiest difficulty all over again. The game will last you about 40 hours on each difficulty (with the expansion). So if you decide to play throughout every difficulty, you are looking at about 120 hours of gameplay time. if you fall in love with this game as I have, you will create a new character and do it all over again. Yes, it's the new Diablo. Yes it is great. If you are waiting for Diablo 3 and have never tried this game, go out and buy it NOW!

"If you like Diablo then you'll enjoy this."
Basically [...] get a game and the expansion that were both originally $30. It's a lot like Diablo only with a Greek Mythology theme. The cinema is good and the environments are much sharper and more detailed then Diablo 2. So if you like hack and slash RPGs then this is a great game to pick up. Also I have a 4-5 year old computer that runs TQ just fine with only a few moments of lag.
