I'm going to be building a website that will contain reviews of games (a particular niche, i'm not dumb ), videos, and a forum. I want the site to flow in terms of design so for instance the header will stay the same for the forum/main site/video area.

What CMS(s) would you recommend?

PS I know my way around HTML/CSS for the most part, but when it comes to PHP, CMSs, etc I'm usually pretty lost. So if it's 'simple' yet still rather customizable, that would be big plus.

For your video site:

I recommend using WordPress with the Carrington framework and the text-only theme from Carrington.

That can be customized easily (I did that on cookielessdomain.com) and it is very flexible.

Customizing a forum is easy if you know HTML/CSS.

Alright awesome. My main worry though is how I will integrate the blogging aspect (Wordpress most likely) seamlessly into the other 2 aspects... So I imagine I will be using Wordpress for both the blog aspect and video aspect, and then probably phpbb for the forum. Since I'll be using Wordpress for the blog and video, those won't be a problem to integrate together of course. Hopefully the forum won't be difficult to 'fuse' with it.

Any other input is welcome if you are wondering if I'm waiting for any more responses... I feel like my post was a little awkward and might not convey that.

You can use bbPress that can be integrated into WordPress easily.

Wow I completely forgot about that... Haha thanks man. This will be easier than I previously thought.

I'd recommended Wordpress with the Starkers theme (easy to customize if you're well-versed in CSS and HTML - very little PHP knowledge needed). Do remember that phpBB will not serve you exceedingly (there are not as many features as phpBB forums as its still early in its development stage). You could also try stripping a video-sharing theme (if that's what you're looking for) and then customizing it.

Good luck with your gaming blog!
