Of course, I would love to have more primate species being incorporated into the game as well; even with the amount of species that we already have. But naturally, each of those things would need to make sense for one to consider on which type of primate Frontier will incorporate into the game the most.
Beginning off with the prosimians. I believe that the game should at least, have one (or two) more species of lemur-like primate; with the Aye-Aye and Coquerel’s Sifaka being two unique species of lemur that I would love to have in the game. Now as for other prosimians such as pottos, bushbabies, lorises, and the like. I would not expect each of those species to be equally demanding in terms of their popularity; but nonetheless, I would love to have at least the Bengal Slow Loris, (or even the Greater Galago) as a possible secondary choice as well.
For the New World primates, there would be a greater amount of different options for Frontier to choose from, if they ever decided to do so. But in terms of personal preference, I would be more than happy to have a widely-varied cast of New World primates being included into the game’s roster. With the Golden Lion Tamarin, Black-and-Gold Howler Monkey, Geoffroy’s Spider Monkey, Central American Squirrel Monkey, and the Peruvian Night Monkey being my preferred primates of choice.
Much like their American counterparts, Frontier would also have plenty of Old World primates for them to choose from, especially if any future dlc were to ever include any one of those particular species. In terms of what I would like the game to include, there might be a fewer amount of options for one to choose from, (given that we already have three species of Old World monkey in the game). But even still, I would expect, at the very least, see one or two of the following options being added into the game at some point. With the Mantled Guereza, Francois Leaf Monkey, Gelada, Hamadryas Baboon, Lion-Tailed Macaque, and perhaps even, the Patas Monkey, all being those preferred primates of choice.
At last, but certainly not least. I suppose that since we practically have all four species of great ape, in addition to the Siamang that was recently added in the latest dlc. I would rather careless if Frontier decided to not add in any additional species of gibbon. But if Frontier decided to do so, then I suppose that adding in either the Lar Gibbon, or perhaps, the Northern White-Cheeked Gibbon would be suitable enough to completely finish off the game’s ape roster. But then again, I would also be more than happy of having the Siamang as being the game’s only species of gibbon as well.
