Finding new games to play oneself, or recommending games to other people to try can be hit or miss. Stores like Steam offer some ability to refine searches which is good. I’ve implemented a suggestions page focussed on the kind of games that I like (story-driven not time or reaction critical Adventure games).
The page remembers aspects selected but this is all done in the browser on the client side (using browser local storage). No data is sent to servers and cookies are not used. Comments welcome.
