Good for getting the first city to get you in the production lead.
Year of Plenty: This card is a bit of a raw deal (you've spent 3 resource cards to get 2!), but in the early game it can be handy when certain resources are hard to come by. Any hand can be built from when you can add two wildcards to it, and you can effectively hold a 9 card hand safely with it. Good for getting the first city to get you in the production lead. Less useful later, but you can always use it to help buy another development card.
