Here's a tough choice: would you rather play a game about a gardening robot that experiments with new methods of character animation, or a ridiculous time-travel action game that throws paradoxical caution to the wind? Lucky you -- you don't have to decide at all. On today's Engadget Playdate, we're playing both: Ubisoft's procedurally animated Grow Home and absurdly silly Super Time Force Ultra. Both are new to PlayStation 4 owners this month and free for subscribers of PS Plus. Are they worth the monthly dues? Join me and Tim Seppala at 6PM ET (3PM PT) right here, on the Engadget gaming homepage or at Twitch.tv/Joystiq to find out.
