This game is fun as hell!. It's like an online cafe style game with a sims style twist to it. You can purchase just about everything that you can buy in the sims games and + it's FREE & ONLINE. Only downfall to it (which i have seen) is that you have to pay for your stuff (tv's , furniture, tile etc) but i figure why pay for it when you can use other people's stuff happy: . I recommend you guys check it out if you have some "spare" time on your hands
