Its a bit of a small kids game but anyone can have loads of fun!
Firstly you'll enjoy lego language. While its in subtitles across the bottom the characters will speak in an odd language where normal words are put in weird orders and has nothing to do with what they are saying. Their favourite phrase is "I will catch you by the tommy!" Which normally means somewhere along the lines of "which way is to the store?"
Secondly you'll enjoy roaming the lego lands. These are of good size and there are 6 (I think) and each has several races, various more different challenges and a boss race when you beat everyone.
Thirdly the gameplay is immersive and silly weapons and building your own vehicle only improve it.
So to conclude its good value, Exciting, Funny and extensive and its cheap to!
