A reason to return regularly would be having enough variety without needing to search endlessly for something interesting. I might settle on a couple of favourites, then occasionally switch things up when I feel like trying something different. I also like being able to find the important sections without wasting time. Having the official site saved somewhere would make things even easier, especially if I already knew there were a few games worth returning to. For me, consistency would matter more than constantly having something completely new.
