When looking for help online, almost everybody seemed to point back to certain strategy guides. I actually tried a few, and although they seemed to help a little bit, they also came with their own problems...
First of all, most Mafia Wars guides are full of fluff and filler (we all know how to sign up to Facebook for goodness sake!). I'm sure these types of guides are useful for total newbies, but let's face it, it's not rocket science getting set up, and I wouldn't be looking for a strategy guide if I didn't know what Mafia Wars was or how to get started, would I?
Secondly, there are some strategy guides that actually give you advice that could easily get your account banned! You would be amazed at some the crazy things people suggest you do, from using bots that technically game the system and the network, through to unethical tactics and strategies to level up, which I'm not even going to mention unless it gets into the wrong hands.
Heck, many publishers of these guides, along with a few websites, will even ask you for you account information! It goes without saying, you should never give it to them!
