What is the difference between WoW, Second Life, and Simcity? Arent they all life simulation / virtual world games?
You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

Second Life is an online social space, that people go to, to hang out. Second Life lets you do quite a lot with creating objects, environments, animations, all on your own, the game's user created content is quite prominent in a lot of areas. Also you can pay real money for Linden dollars (the in game currency) and give other people money for the content they generated.
Simcity is a game that you're supposed to derive enjoyment out of, from managing a city. It has little to do with the other two games on the list here. You build and run a city, by yourself, and that's about it.
All 3 of these games require downloads/installation processes to be able to run on your comp. There are plenty of browser based MMORPG's and online spaces/flash games that attempt to do the same things but for free.
Fusionfall's a good example of a browser based MMO (Run by cartoon network).

Habbo Hotel is a free browser based online virtual space to hang out in.

M$Which of these need to be downloaded and installed and which of these can be played online without downloading anything?
All 3 require software to be installed. WoW has a trial for free, but there is a huge download first.

Second life has a smaller download and is free.
