An exciting and somewhat challenging game iMobsters fun starts degrading at around level 50 or earlier. While the developers are consistently adding new features to maintain the user base there is just limited potential in a text based game. While a good game to play to kill some time I wouldn't consider the game a whole lot of fun. Additionally, it's challenging aspects can for the most part be easily come by certain strategies.

Pros:

Various strategies you can develop to come out on top

Various bonuses for completing missions

Growing user base

Frequent game updates with new weapons, missions, armor, and other updated game elements

Cons:

Users can buy their way to the top and easily over power you.

Very repetitive

Text based so limited graphics obviously... gets kinda lame after a while.
