The monsters are really funny. They don't have the "too cute to kill" look but you might get an odd feeling after slicing a Lawn Gnome in half with one of your sword rings.
The only major problem is the LAG!!!
zOMG! lags a TON, there are ways to reduce it, but even with them there is still a lag issue with the game. If this gets fixed though zOMG! could quickly become an amazing MMOrpg.
Here's a nice 8.0 out of 10 (4 out of 5) for ya from Lord-MMO a (fairly) active zOMG! player
