That is exactly what I was thinking. Licenced themes like Star Wars are needed (even though It's too repetitive in my opinion. How many more Millenium Falcons do we really need? While I am a fan of the SW movies, I kinda dislike the LEGO theme.) But lines like Angry Birds or Ben 10 are absolute trash, just LEGO playing safe instead of makeing their own themes.
Where is Racers? Where is Castle? Where is Space? all those themes that made LEGO what it is today are only remembered by true LEGO fans. Every other LEGO "fan" has forgot has forgot about them.
I have LEGO Worlds on my PS4, and I have to say, it's probably one of the best LEGO Games. In fact the LEGO Games based on original themes are superior in my opinion then the Licenced ones (although I still enjoy them). and let's be honest: Who has ever asked for LEGO The Incredibles to be a LEGO Game? I was shocked when I heard it was going to be a thing.
