I love the Sims 3. It's has the most content and mine never really did lag too much. I just had to disable the Into the Future expansion. The legacy challenge is what kept it fun for me. Sims is one of those games where you play hardcore for a week then go on a six month hiatus. At least for me, that's how it always happened. Then of course, every time I came back, I would start0 fresh and basically repeat the same thing using the same sims and the same house and it became very repetitive. So I went online to look for ways to make my gaming experience more fun. I discovered the legacy challenge. There are all these little rules that make it harder and I had way more fun following them and making sure everything went according to my plan. I wanted to recreate my family tree, so I did some research and my grandpa told the names of our family going back ten generations! I kept all the siblings and married them off and moved them out. To do this, I made the lifespan relatively short so I could get through the generations without becoming too attached. This also gave me something to look forward to: my birth. I am on the ninth generation now and my dad is still a child. I can't wait for him to grow up so I can finally join the game with my own sim. I am the last generation, though, so I'll probably lengthen the lifespan and play like I used to before the challenge.
