Highly addictive sandbox game, is quite unique because of it's lego-like quality. Is it worth it timewise?
Minigames are fun and highly addictive when you are with a lot of people. There can be a ton of objectives, or just a simple all-out brawl between characters.
The only flaw I find in this is how long it would take anyone to build anything big. They would have to be a person that, frankly, doesn't have a social life. Unless of course, you are building with a friend online.
Yeah, the $20 price is worth it if you are just looking for a release every once in a while, but I don't know... there isn't much potential in it if you are going to be playing it hardcore. (not that you really can)
Thus, comes into play, my rating of a... 7
