This game was definitely fun. I loved it was DC themed, and of all the characters there were a bunch. Like any Scribblenauts game you can create anything with a book. The story line is good, and how much story there is. I like that you also can teleport to different areas in the DC universe, and I gotta say it's cool. Another good thing are the side missions. The side missions are little things you can do to earn points. You can use those points to buy costumes, worlds, and the Justice League's backgrounds I believe. The cool thing about side missions are that there are a lot of different variety of them, and when you teleport to a world and back the side missions change. For example when you teleport from Metropolis to the bat cave, and back to Metropolis the side missions change in Metropolis. Another thing you can do is specifically ask for a weapon. For example you can ask for green Arrows bow, and it will give it to you. Same with vehicles, and characters. The last cool thing you can do is customize your character. You can make just about anything in the character customizer. Like someone made Deadpool. (Picture on bottom of post). The coolest thing in the game that I've noticed is that you can add adjectives to the selected item that you click. In the end this game is FULL with creativity, and cool stuff. I also suggest for you to try this game out, and try their other game like Unlimited, and showdown.
