It was fun as a kid but I don't really see much reason I'd play it now.

Especially since there's been so much added content that doesn't actually change the game in any way. There's like seasons with cosmetics and new game modes and daily challenges and missions and... does anyone care? The whole reason this game was appealing back in the day was because it was simple. Just run as far as you can. This game is trying to be Fortnite or Brawl Stars or something. The core gameplay loop does not have enough depth to warrant any of this.
