http://en.wikipedia.org/wiki/SimIsle:_Missions_in_the_RainforestSomeone here must have played this Maxis game, I'm sure. This was the very first management game I ever played, back when I was a wee teen. Ahh, that boxart... so pretty. :3
It's markedly different from other citybuilders, as you need to hire 'agents' in order to build specific things. I forget the exact types, but I'm pretty sure there's biologists, ecologists, engineers and such to do different things for you. Resources are things like lumber and oil that require the proper facilities to refine.
It was sort of an edu-tainment title, with factsheets and videoclips within the game of the natural (and manmade) rainforest environments. But it wasn't done annoyingly. The gameplay was actually very fun, with lots of scenarios, and I
think it had a random map generator (can't remember exactly) but it did have quite a few stock islands to play on. And besides the pre-set scenarios, you could also play in sandbox mode and do whatever you like.
There is exactly
one video on Youtube for this game, so
here it is. It's the best, briefest, blurriest example I can show of the gameplay. I might actually try recording something myself if I can get the game working again.
Edit: Also, I believe this game is freeware by now, so Googling it should result in several download locations. Uses DOSBox, I think.
