After the uneventful Saturn era, the series found renewed popularity during the sixth generation of video game consoles. "Sonic Adventure", though criticized for its glitches and camera system, was acclaimed for its visuals, spectacle, and varied gameplay; "Sonic Adventure 2" was met with similar praise. However, journalists began to feel the series was straying from its roots, with some commenting that "Sonic Adventure" failed to reinvent Sonic for the 3D era as "Super Mario 64" had for Mario. Stewart argued that "Sonic Adventure" addition of voice acting and greater focus on plot changed Sonic into "a flat, lifeless husk of a character, who spits out slogans and generally has only one personality mode, the radical attitude dude, the sad recycled image of vague '90s cultural concept". Edwin Evans-Thirlwell of "Eurogamer" agreed, writing that Mario's "plucky earnestness and whimsy will always enjoy a longer shelf-life than [Sonic's] over-compensatory edginess".
