So far mine has been the Dwarf. Sure he can't ride a horse, but it is fun to play the dwarf and dang it, I like his pseduo technlogoical bent.
One thing I really like is all the classes are unique. Very cool ;)

Dwarf is the only class so far I've made it through the whole game with, I ended up with enough speed bonus items to not require a horse in the end.
But, not knowing the game at the time I did it, I put points into worthless abilities, ack.
Currently replaying as the Seraphim, just to be geeky and eventually grab the hidden lightsaber weapon available only to that class.

ive finished the game using the gladiator and the seraphim.
of those two i prefer the gladiator because hes just a typical hack and slash char with no finesse really needed. just brute strength,

Only played with the Battle Mage so far. He's cool, but seems a bit overpowered. Enemies become way too easy to beat way too quickly. At level 15, I can only be defeated by large mobs and only if I forget to buff before entering battle.

I started an online game with a seraphim. very cool, enjoying it so far. i've messed around with the other classes, but the dwarf and seraphim are the ones that I'll play through the game with.

I managed to complete the main game with a wood elf. Loved her comments when you where killing mobs.
Thinking off playing the vampire now that i just bought the game again.

I love the Battle Mage. I love casting spells. I love the fact you can cast spells on other members of your party too. Thats soo kool.
BATTLE MAGES ROCK

Vampiress Knight. Seems like a unstoppable killing machine in my playthough so far.

Battle Mage, ftw! I know everybody else loves 'em, but there is something satisfying about casting multiple purgatories on mobbing goblins. I swear, goblins are worse than a raving, mad crowd of English soccer fanatics.

lol how do you cast multiple purgatories?

I don't combo them, but the spell recharges fast enough that I can get about 3 purgatories at the most

Deamoness has to be the best :)
and I found a neat dragon killing trick - use her winged form and cast the fireorb spell (i forget the name but the spell which makes an orb which fires out firerays). The winged form makes you fast enough to avoid dragonfire and also metor attacks - whilst the orb allows you to hit the dragon without having to close with it (and its sharp claws) and also without having to stop to fire a bow.
It takes time but it kills them off :) you will still take damage though

The Daemon had me the first time I flew over a river :)

I dunno..I have no class!
*With respect to Rodney Dangerfield.*

The only character I have played so far is the Dark Elf. He's awesome. I always go for the the dual wielding agile type chars. I think it started with final fight, when my brother would play as Haggar, and I would play as Cody.
