I've lived and learned that some things are better left in the past.
I have fond memories of Sonic Adventure 2. The revision, Sonic Adventure 2: Battle, was the first game I ever played on a Nintendo Gamecube, and I remember that moment very clearly. At the time, I swore it was one of the coolest games ever. Running down the side of a building at high speeds? It was awesome to me at the time. On top of that you had two parallel stories that lead to an epic final chapter. I made it a priority to eventually own the game and I did, and I enjoyed it a lot. From the campaign to the Chao garden, I spent a lot more time playing Sonic Adventure 2 than I should have. Looking through the lens of Sonic Adventure 2 HD, it’s kind of hard to see why I enjoyed the game so much in the first place.
