A free download can still cost an evening, storage space, attention, and a place in your routine. The right first question is not which game is biggest. It is which activity you want to repeat.
Name the fantasy
Do you want to build a roster, explore a city, command a fleet, or engineer a frontier? A clear fantasy filters the list faster than comparing feature counts.
Watch ordinary play
Look for unedited menus, travel, resource collection, upgrades, failure, and repeated encounters. Highlight footage shows the reward; ordinary footage shows the life of the game.
