Out of curiosity, are you on a phone or a desktop?
For desktop users, it strikes me we’d be better off like if we laid it out like this:
Then at least the list is visible as soon as you hit the page (and the layout feels more familiar).
For phones, those users are perhaps more accutsomted to scrolling down to find anyhow?
I agree that, aside from the layout of this Tab, the “Custom Games” label is “hidden” in the way that stonedefender says.
I wonder if it should in fact be a button “More Games” … or something, so it is not overlooked.
