Because, just like you are entitled to whine and moan about the game, we're entitled to praise and cheer about the game. Also, you're really not contributing to the thread at all. If you feel that it shouldn't be here, report it and move on.
Anyways, I would rate the game an 8.7. It's interesting and fun, but I don't see it lasting me awhile (until my friend is able to play, anyways). Once PvP is added I'm sure that my score will go higher.
