This game is very enjoyable but you don't have very long to try it out.
The areas and NPCs are creative and colourful and there is a wealth of ways to uniquely customise your characters. You can also buy lots of different armour and weapons which you will need to battle the evil guys which of course get more powerful as you complete quests, level up and move on to other areas.
It controls just like other MMOs and this works well and it's fun interacting with other players.
I think you should go check out this awesome game for free while you still can and make the most of it if you are a fan of the Lego games or just MMOs in general.
