I had three goals left.
First, get enough candy to max out my 100% and 98% Tyranitars (did that a couple weeks ago). Although I'll need more if I ever hit level 38.
Second, reach 10 million experience (did that a couple days ago) since I'll probably never hit level 40.
Third, finish my non-regional pokedex before gen 3 comes out. The only things I still need are Flaaffy and Ampharos, but it's incredibly hard to get candy for them, or to get any worth evolving. I finally hatched a Mareep a few days ago (got the egg the day after double candy ended), but it only had 10/10/11 IVs and gave me just 22 candies. The one I already had is 12/10/12, so not much better, and I'm very reluctant to spend over 70 rare candies to evolve it, even if it is my very last goal.
