The offline maps aren’t the same as the online ones, unfortunately. They’re significantly smaller, and they are fewer maps in offline than in online. Same for the game modes, fewer and lamer than online. Offline is meh. (But IIRC, every character is unlocked for offline play?)
Thank you for letting me know. That’s such a bummer honestly as it’s on sale for eighteen bucks at the moment. It might be better just waiting for Lego Star Wars and put it towards getting the Deluxe Edition as having the blue milk Luke minifigure and Rogue One characters DLC would be a lot more fun for roaming the galaxy since the game itself appears as though it will be the full game without any updates for new content. It’s a shame though that things are all DLC these days.
