Really cool concept and cool art as well. Well done.
Have you thought about fence variations?
Have you also thought about it as areas just in the ocean? Utilise that Ferry from Jurassic World mayhaps.
Have you also thought about the unlocks situation in regards to aquatic parks? I would think that having unique Research, Exploration and Fossil buildings for aquatic parks might be better so you can make the process independent of land parks.
Thanks
The fence I showed here would be 1 of 2 variations. 1st variation, shown here, would be similar to the light steel fence in the game, the 2nd variation would be the same as the 1st, but double layered. I thought of using steel meshed fence since a concrete wall in deep water doesn't seem logical.
The ferry was originally my plan for this DLC idea where visitors arrive from, but figured I use the arrival monorail instead since its already in the game. The ferry arrival can be an good option though.
As for the unlock situation, it can be same as the unlock process in the land parks: complete missions, reach a set division reputation, etc.
With the Research, Expedition & Extraction of fossils, I figured, why design new structures that can do xx-type of tasks, when there are already structures that can do xx-type of tasks, thats why I thought of making research, expedition & extraction as off-site functions provided by the other parks. I was also thinking of making a concept building, a Communications Center: which functions as a relay point where players can request off-site fossil expeditions & extractions, as well as request other island parks to do research.
I know the benefits of adding independent & unique Research, Exploration and Fossil buildings for aquatic parks bring, especially on building diversity, but, there'll be no challenge since everything is given to the player, thats why I thought of making it an off-site function, to give players a challenge, as well as ease the workload on the developers. Either way, its just my opinion.
