Carl’s Guide to The Sims 3 Ambitions Carl’s Sim 3 Guides is perhaps one of the biggest, in-depth guide to the games from The Sims 3 series.* Ever since Ambitions released, they’ve been hard at work creating a walkthrough guide for the expansion.** If you’re not familiar with the site, I encourage you to check them out – they cover objectives like inventing, sculpting, baking, the various professions and even how to get a SimBot!* Make sure you check out the rest of the site and bookmark it – you’ll never know when you may need it!
