I think it's a game you can play again and again. Besides the sheer joy of simply progressing through the main quest, there are numerous other incentives, such as beating the game in Hard Mode, acquiring all the time attack items, maxing out Wander's health and "grip gauge," and even just exploring the landscape. I'd already played the game three or four times before I noticed that huge scary tree atop Colossus #10's lair.
