For sure. I know it's not what most of us here want to hear, since we're probably a bit more inclined towards animal interest, but after the conservation pack, there are no more terrestrial animals that are a big draw to bring in or keep new players that have a more limited interest and knowledge in animals. If the game is going to continue on past this year, I do feel like Frontier is going to have to release something that'll grab those casual player's interest, and that's either flying or fully marine animals.Exactly this. Though the official forums are great and have some really avid fans, they can sometimes turn into an echo chamber. What’s popular at the moment on here may not actually be what the PZ community at large is wanting to see/get.
I also agree that if Frontier is hoping to sustain/increase DLC sales for PZ, they are going to eventually have to introduce flying and/or fully aquatic species. The general public more than likely isn’t as interested in more “niche” species as we, the zoo fanatics of the forums, are.
Most of us here would probably buy just about any pack, but I also think that we are not the majority of the game's players - by far. As popular as the Tasmanian Devil and Maned Wolf, etc are here, I just don't see them grabbing people's attention that play every so often. Zoo games have a rich history of having marine packs, and even though I'm more ambivalent towards one (team bird here!) I recognize that it would have a large amount of appeal. Whales and Sharks would be that "new shiny" that brings the casual player back to play, and more importantly, bring the money back.
