That 7/10 score comes from hands-on play where the sandbox mechanics shone in letting me craft my own chaotic narratives, but it dipped because the pacing sometimes dragged in quieter moments.
What nailed it as the "Parody Sandbox Game" was driving through neon-lit blocks, picking up hitchhikers for unexpected twists that echoed classic open-world chaos but with an adult edge—think high-speed chases ending in hidden alleys. I've sunk hours into tweaking my character's backstory, and those personal touches made victories feel earned, not scripted.
