The two goals of my first hunt were kudu (I shot 2) and a cow buffalo. Kudu had been at the top of the list for decades; the buff opportunity materialized late in the game (I got one).
But to your question... I think you're asking what wasn't on the list before but now is, assuming I make it back. For me there are a couple. I had zero interest in a black wildebeest when I went over (zero!); they are close to the top of the list now, after having watched them while hunting other stuff. I had only tepid interest in nyala. After seeing them, they are much, much higher on the list. I had no real interest in zebra or warthog. Zebra was a part of my original package and after hunting and shooting a nice one, I'd happily hunt one again. If we had them in Alaska, they would be what I targeted because I enjoyed what I had so much as table fare. I shot a warthog as a low cost item late in my hunt, and, after seeing one up close, I'd happily give dedicated time to finding a good one on a future hunt.
All that said... Kudu will be on my list every time. I am delighted with the two I shot. I want to hunt them again.
