Game Rant's Riley Little writes, "Ubisoft released quite a few titles during the Nintendo 3DS’ launch, and Combat of Giants: Dinosaurs 3D happened to be one of them. This game is filled to the brim with everything that fans of monster battling games (i.e. Pokemon) will love, as well as some nice visuals that make some solid use of the 3DS hardware.
However, the fun that can be had with Dinosaurs 3D is extremely short-lived, mainly due to the generic and almost painfully boring gameplay. Kids may find joy with this title, but it won’t hold their attention for more than a few hours."
