Are they fun? Not too childish?  I'm looking for the movie one  coming on PS4 soon but not sure about it...

they are ok, a lil bit of basic action and some puzzles and collectables
if you never played one they are better because every game its pretty much the same with small variations

Theyre alright alone, tons of fun with friends.

Star Wars Complete is fantastic. One of the best games of the generation.

I have Lego City Undercover and that game is fun and very very funny. If you like funny game that aren't inappropriate, then they are for you!

They are a lot of fun if you are a collector and love to unlock stuff. I really love them a lot :).

I like the lego games, they are a bit on the easy side but provide a lot of fun and replay value. I am getting The Lego Movie Video Game also.

Undercover was awesome and my first lego game.

Thanks guys, looks like a buy then.

I've only played Lego Starwars game, but that was a long time ago.

Don't you mean :

a long, long time ago...
