I'd LOVE some new recipes! I love cooking in the Sims, but it starts to get a little bit boring after you see all of the recipes. I'd love it if there was a toaster to make plain toast, then you could decide which spread you want, if any. Also, maybe we could get some more non-alcoholic beverages?
I think it'd be pretty cool to have a skill tree, but it can already be difficult to decide which path you want to go on in The Sims. It might also make you miss out on some important skills and abilities.
