These sound a little like games I use to play on FB ~ Farmville and Castleville.  On there you do have friends to send you requests but the farming one was so addictive at first.  You plant crops, build your farm, etc. They got to where the requests were so time consuming that I ended up playing before work, sometimes at work until they shut down our link, and then after work.  Didn't have time for my "real" games that I paid money for and they would offer really "cheap" packages of coins, whatever.  You didn't feel like you were spending much money but decided to just quit them cold turkey as it was starting to be hard to level up and I wasn't willing to spend a lot of money.  Haven't missed them.
