Each time I am in the planning stage of a safari, the outfitter or PH will bring up dietary requirements, where I respond "During the x days I'll be coming over, I'll be allergic to beef, chicken, porc, lamb, etc. Only game meats". I love trying out new things I have not tried before.
Haven't eaten waterbuck yet, and reading all the comments on keeping the oil away from the meat, also brings me to another observation: Most 4-legged animals can provide a satisfying meal, provided they are:
1. not too old
2. not in the rut
3. not too much adrenaline from the chase
4. not shot in the gut
5. killed cleanly and rapidly
6. butchered by a professional
7. rapidly being cooled
Tastes will of course differ, and the food the animal typically eats will determine a lot. Picky eaters will typically produce finer meats than those animals that will eat just about anything.
The tougher the meat, the longer you'll need to cook. Elephant kebabs are great if well done. I tried them medium rare, it is unchewable.
Favorites are Eland, Zebra, Kudu, the Wildebeests, Oryx, impala, etc.

@rookhawk 's recommendation: "Puffadder", aka Eland colon, filled with pieces of Eland filet, liver, heart, fat, spices. Absolutely wonderful.
Elephant kebab's: cubes of meat from the top of the shoulder, interspersed with cubes of fat from behind the eyes (and the occasional piece of onion).
