This genre of game is still really popular, and copied a lot because of it. If you are a regular reader here at 148 Apps (*waves hello*) you may have come across my slight obsession with this style of game. I love playing these pick up and put down games because it means I don't have to commit to huge story lines or collecting little bits of things that I will forget what they are for. This game you can jump in and jump out again, which suits me fine."
