I like the video games, and I buy a lot of Lego Friends toys for my daughter. I also have a Chase McCain set that was made available to buy when Lego city Undercover released on Wii U, In which the number plates on the vehicles had codes to unlock some in game content.
Surprisingly, the LEGO games are rather fun. I have LotR, MARVEL, and Dimensions as I mentioned earlier. But it's the licensed franchises and not LEGO itself that attracted me to these titles. My most compelling justification for Dimensions is Doctor Who. Playing the Doctor Who section during the main storyline and the level pack was a real nice treat. I've only sampled the open Doctor Who world so far, but all have paid homage to the Doctor Who universe.
