I did really enjoyed the old Lego Creator, Lego Racers, Lego Island 1 & 2, and Lego Rock Raider games.
As for the Lego games done by Travelers Tale,
I played quite a few of them and am not sure which one I like the most.
The Lego Starwars games were fun. Also the Lego Lord of the Rings are great too,
I also really like how it had an open world. (Ride horses throughout Middle Earth in search for secrets? Yes!)
I am thinking of trying the second Lego Batman game when I see it on a sale.
