I absolutly love the Sims franchize. I originally had the first along with the SuperStar expansion. This was a game I personally enjoyed. The funny simlish talk, the actions, and despite the not so good quality, for a simulater, it was a great game. I've never gotten the chance to play the second game. But I've watched TONS of series involving Sims 2. I want it badly. But my friend said she would find her copies and give them to me. I'm crossing my fingers XD
When it comes to Sims 3, I want to say, to some extent I am a bit disappointed with it. I feel that EA didn't put enough effort as Maxis had. Don't get me wrong, I love the graphics. I have all expansion packs up to Pets. Not to mention I've modded the heck out of it.
Originally, I used the first Sims to have fun and go thru a sim life. But for Sims 3, I find myself more drawn to making houses. A large majority of the mods are decorations for houses. I absolutly adore making houses. I think I make them more than I actually play the game. And when I do actually play, I'm killing off my sims and just playing as the pets XD
But gawd! I can't wait for seasons! I'm jittery just thinking about it. X3
Edit: Also about the Sims 4 thing. If I remember correctly, a Sims 4 url domain was licensed by EA. So it is unclear if the game is in working progress atm.
