Your images aren't well optimized in the game views (e.g. www.gog.com/games/spellforce_platinum). I suppose it could vary from page to page but medium-sized jpegs that are doubling as thumbnails shouldn't be anywhere near 500K. That's crazy even on the desktop but you're not swapping in lower-res images at the lower-res breakpoints which is going to make viewing this site on a smartphone or a tablet a very slow-loading/frustrating experience if you're not branching them at the server somehow. I don't have an amazing connection mind you but it's respectable DSL and it's been a long time since I actually saw basic content images loading in chunks down a page on a regular basis.

Also I have no idea why you would want to add the client-side best practice and performance-murdering, arbitrary layers of needless abstraction that solve no real problem foolishness that is Angular.js when (even if you disagree with me on most of that) you're not even running a single-page-app.

But hey, you pulled off a responsive layout without Bootstrap so props for that.
