Right up against iMob Online was PlayMesh's iMafia, which allows for similar gameplay functions but with more of a graphical interface.

iMafia has gone through three incarnations, as have all the iMafia franchises like
Legions of War or
Heroes III, and now is in its most complete version: iMafia III. With
iMafia III you get a lot more detail in how you can level up, including how you level up specific missions and weapons. Beyond this you have secrets placed in maps, a much more complete way to customize yourself, and a property system that is great. What is really defining to iMafia III, and all of PlayMesh RPGs, is that it does not use a code system like the iMob Online Friend Codes. Instead it forces you to buy mafia members for your mob using real money or
iMafia III PlayMesh Points. You are still required to add to your iMafia III mob, but you cannot do it by adding other players. The iMafia III PlayMesh Points system is provided with a lot of options, and you can use these iMafia III PlayMesh Points on things like more mafia members and money. The iMafia III PlayMesh Points are also given away as promotional offers frequently, so you can expect free iMafia III PlayMesh Points often.
