Which content management system for a game fansite?

I'm going to create a website around a famous game. I expect to have around 50k UV a month in about a year or half.

I'm looking for a suitable CMS for my needs, which are:
- I need a news homepage
- I need a forum board
- I need the CMS to be SEO friendly
- IT HAS TO BE NOT VURNUABLE TO HACKER ATTACKS
- Ability to add articles
- Ability to add videos
- Ability to add social features (I LIKE IT etc.)

I am taking Wordpress (with thesis theme) and Joomla into consideration.
If Joomla, which theme should I use?

If wordpress, how to create a nice forum board? Maybe I should use other script on a forum subdomain? WILL THIS NOT CREATE DUPLICATE CONTENT PROBLEM IF I WOULD MOVE ARTICLES FROM FORUM TO MY WEBSITE?

Maybe you know some other CM systems that I should consider?

PLEASE HELP ME! Thanks in advance for all useful posts!

 

Wordpress with thesis good and my friend use Migle Forum plugin for his forum board

 

Hi Friend,

I am suggesting you to go with Joomla cms or Drupal cms both are most popular in the world and which support you any kind of features support like forum, latest news, game module, video gallery, image gallery, shopping cart, blog and more and more....Am into this industry from the past 5 years. you can choose joomla else drupal which support you seo also. you can manage your site like edit, add, delete and more.... for your information if you need am happy to help you to build this website .

 

Yes, I recommend you use Joomla too. However, Joomla can take you time and cost to make a great theme but Joomla seems not doing SEO well.

 

Drupal should satisfy most of your requirements.

 

I suggest you Joomla
