hnnnngh Just so you know... competitions like this are horribly despised in design circles (no prize even...seriously?) - mainly because it undercuts professionals who would charge a few thousand for a high quality logo, and also usually results in & promotes a very very low standard of design. If you're after a good logo you should really pay a professional to produce one (in other words - you get what you pay for). Jus' sayin'..
That said the submissions by Neshil and bc are both quite good, probably prefer bc's as the typography suits the tone of the diablo games.
- Don't use clichés. I know it's tempting to use Exocet (the original Diablo UI font) or some other gory fonts, but try and break it up a bit. A brand can really stand out from the competition if it surprises the user with a fresh approach to the idea. There are, of course, a zillion theories on how this is not true, but I am in the "surprise-user" camp.
Although Exocet might not be perfect, I think it's incredibly important that the typography is considered with relation to it's context. I don't feel that your submission of a modern sans-serif suits the gothic mood of diablo, it's probably best to use a serif typeface of at least something with a "sharp" feel to it.
Keep in mind I am not at all suggesting the use of novelty/display fonts...everyone please try to stay away from dafont or similar sites - it is the very height of unimaginative font choice...
Here is my attempt I created a vector image From scratch so no worries about copyright infringement used an edited Blade 2 font for the Diablo feel hope you Like it I have a layers copy if you need it this is the jpg...
I like the idea of a single symbol that can sort of identify the site. This is a pretty rough sketch, but working with some kind of symbol like that we can have infinity logos and titles and stuff because it could be easily adapted to many roles.
So yeah, the actual GD elements of this are bad and will change drastically, but that main icon is what I'm talkin' bouts!
