I have been working on this idea for some time now but before I continue with it any further I want to put out what I have so far, to see if it's worthwhile and also maybe for some feedback and advice. This is just the idea, not a sign-up sheet or anything in case you're wondering.
I've been doing a lot of backstory on the aliens called Amorphs (who also feature in another story I'm writing) and in this RP idea they feature as the aliens who abduct you, the participant, to live on another world reserved for endangered species. Humans are 7 billion strong, but the Amorphs foresee their demise (I don't want to spoil how/when/if it happens) and take a carefully selected sample of what they determine to be the strongest individuals. As well as the genetically strong, fit and athletic they also bring those with less physically orientated talents, such as leadership skills, intelligence, scientific knowledge, trade skills such as joinery, etc. Every character has a useful strength that would benefit a new colony of humans for generations to come. Just no superpowers please. Normal real skills.
But aside from being a rescue from extinction, you have little to look forward to here except living out your life in some jungle, never knowing how you got there. The Amorphs don't communicate with you, they think your language is too simple, too one-dimensional. To them, i would be like you trying to have a conversation with a dog using doggy sounds and gestures. They also don't think your little pink squidgy CPU could handle the truth of what has happened (or will happen, if it comes to pass)... and in the case of some individuals they would probably be right. No, to them, you might make a good pet, but never an equal. What they fail to realise is that you were no mere ant living in a sophisticated city ant hill. The intelligence of your species far exceeds the stereotype Amorphs developed of humans being insatiable, violent, sex-addicted grease-monkeys.
You have been placed on an island continent that is an odd mixture of Terran life and life from other planets, strangely living together in a working ecosystem. The Amorphs have selected the plants, animals and other life that work best together in a jungle biome. There are other biomes elsewhere on the planet. You will find yourself in a colony of around 50 other humans, just placed there to fend for thelselves and each other.
You can be whoever you want - human trying to escape (or maybe you don't want to leave?), another alien perhaps who was also abducted and brought here, or maybe you could be an Amorph ranger or scientist, trying to maintain order and prevent the humans from escaping.
I will have a map with different locations set up with sites of interest, each containing things, technologies and transport that you will need to escape. You can also make up your own sites of interest and explore, as long as they keep with the spirit and themes of the RP.
Amorphs are amorphous like an amoeba, can float and feed on electrictrons, sand, metal and other trace elements by absorbing it through their ever-shape shifting mirror-like skin. They need to wear super-cooled air-tight robotic suits with an artificial atmosphere in Terran conditions. They are actually fundamentally good, empathic beings but humans are just so alien to them they fail to recognise our potential. They can communicate with each other wirelessly (telepathy) and are highly sensitive to each other's emotions, it's why they're so organised and understanding of one another. But they fail to be able to use their telepathy on humans and other carbon-cased life.
This is really what I had so far, as I said I just wanted to make sure it was worthwhile developing this further as an RP?
