Tim Schafer, mannen bak spill som Day of the Tentacle, Full Throttle og Grim Fandango, har fortalt litt om hva han drømmer om for fremtiden. Han har tydligvis latt seg inspirere av Grand Theft Auto V, og forteller at han har lyst til å legge Grim Fandangos oppfølger til en åpen verden:
"I've had this urge to make a fully 3D version of El Marrow, where it's more like an open world game. You're running around the city and stuff. Games like Grand Theft Auto have a lot of the elements of adventure games, and if there was just an inventory that wasn't guns, you could probably do a full adventure game in one. That's something I've thought about since the '90s."
