I am very sorry to tell you that you cannot only not play The Sims Online for free, but you cannot play it at all. The game was discontinued a few years ago. Sorry!
As far as my knowledge, you cannot play the Sims online. I am a avid Sims fan and have all the games including World adventure. You can purchase the Sims and download it digitally and play from your computer.
While many sites offer the Sims as online play, they require you to install tool bars and/or other items which contain adware. You can find more information here: downloadme.info/files/Skulptura_The_sims....
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
