A game list page/browser. That allows you to sort games and turn on or off specific category.
EX: checkboxes for "f2p" "shooter" "browser" (SHOW) then checkboxes for (HIDE) "discontinued" " "2D" "2.5D" "2000 and older"
sort by : release date or /install size / or even playerbase. ascending/descending
can also add game rating system EX : Video 3/5 stars. sort by
(and have the fans rate the games in the list?)
and have a game of the day/week that you request players to test and rate with a ratings checklist
