The first Sonic Adventure was one of, if not the best Sonic games ever. But this, this is just... bad. There's no hubworlds other than the Chao Garden, the plot is confusing and boring, the voice acting is awful, and most of all: the treasure and mech stages are tedious and slow. They eat up most of the game across both Hero and Dark Story and, in terms of gameplay, are completely overshadowed by the Speed stages, which are 10 times more fun. If the game were all Speed stages, I'd instantly raise it to maybe a 6/10. But as is, this game is such a slog to get through, and ESPECIALLY to 100% complete.
