You know, I'm trying to plan out a first-person adventure/horror game with sci-fi elements, with my engine being Unity, and I'm actually surprised by the potential logistics of potentially needing to set up a team to work on it, mainly due to the asset store stuff. Granted, I'll probably not be buying any of that stuff anytime soon, since I'm more or less completely broke, though there are some really cool stuff in there, including ProBuilder and Relief Terrain Pack. I'll probably get a Kickstarter going, but only after I've got a proper demo prepared and most if not all of the game world at least blocked out, so it is essentially playable from start to finish for the most part.
Basic concept: You're an investigative reporter visiting an island run by a cult, lead by a seemingly friendly leader who is actually more tyrannical than he lets on, and the cult is preparing for a Jonestown-esque mass suicide to facilitate a mass brain upload to a collective consciousness. In order to stop this, the player needs to work with an undercover Interpol agent, talk to the robotic 'servants' of the cult leader, who are programmed to turn psychotic and hunt down and kill anyone who leaves the dormitories at night. Unfortunately, you need to actually leave the dorms and search the island's facilities for evidence and other tools to prevent the mass suicide, and in order to stop the servants from coming after you, not only do you need to help them with their mental issues, you have to incapacitate them at night to hack them and remove the malicious programming.
At the least, though, I'll need to recruit an artist/modeller/animator to do pretty much everything concerning the visuals (and maybe another programmer to reduce the individual workload, I'm not the best programmer, really), though right now I'm more concerned with trying to get the basic mechanics up and running first, and fleshing out the narrative. We'll see, I guess. I would like to find help sooner rather than later, though.
