One of the defining qualities of a truly great game is how long it can hold your interest and keep you engaged. For example I bought the Game of the Year version of Skyrim about 14 months after its initial release. Hence I had access to all the games content that I dutifully played through. However, I also fully explored the world map, completed all side quests, crafted, furnished several houses and continued to travel the in-game world and killing foes long after I had completed all the traditional content. I did the same with Red Dead Redemption 2 as this also offered a compelling and immersive world. Games such as these have a quality beyond just the functional. I would happily traverse the mountains in Skyrim and watch the sunset, revelling in the ambient music. Similarly, I would often just ride the train in RDR2 and watch the world go by. When I finally stopped playing both games for newer titles, I felt a sense of sadness when I bid them goodbye.
