Playable, entertaining, but not something addictive.
Whenever I play my copy, it starts out with the GAME OVER screen; I don't know if it's a glitch or something, but I just hit start after that. Well, the gameplay in 3D World-Runner is in a third-person view. IYou know, 'm gonna' call the World Runner Jack, because my cat's name is Jack. Anyways, Jack is running around, 3D World being a runner, dodging stupid assholes in your way, and I guess the world had like construction problems 'cause there seems to be holes everywhere! So you have to time your jumps JUST RIGHT to get over them.
Little monsters come out the holes to try to kill you, and I keep asking myself, "What the hell do these monsters think they are?! Jack didn't do anything to you! He's just... running! Leave him alone, assholes!"
Well, to sum it up, it's really a game YOU gotta play. It's really hard to review do to odd controls, not BAD CONTROLS, just, no other game has controls kinda like it. Buy a copy off of eBay for like $6, and you'll be entertained, I bet.
