I’ve found that Pandemic 2 is INCREDIBLY addicting. The primary goal is to eradicate the human race with the perfect disease. While the original game didn’t go on to become hugely popular, Pandemic 2 is more an improvement upon its predecessor than a sequel, with an improved interface and more features.
If you’ve never played it, I highly recommend it if you’re looking to waste some time.
Also, what’s the most addicting browser game you’ve played?
Pandemic 2 is a game that if people will like it then they will become very addicted with its sequels also, but if some one will not like it then they will not play even a single level of it.
