Thanks for the comments everyone and I generally agree; this 'species' is very human-esque and certainly follows the stereotyped 'Grey' alien image.
Without going into too much detail about the general background to the idea for this game, it's worth saying that the intention is to create one or two key enemy races that fit this stereotype with the rest of fauna being far more 'monsterous'. I spent a fair amount of time playing around with the EA title 'Spore' and have a pretty good idea how to mix it up for some of the other species
In this first case the species is more human with a greater use of technology and telepathic abilities so I've tried to keep the asthetic and style close to this pre-conception. I hope it will make it easier to identify with them as an archetype or species.
If I may bring it back slighty towards the original 'Game Play Prototype' topic that I set when I kicked this off its maybe worth mentioning 'meta-gameplay' here, as it in someway might help outline the scope of the enemies planned for creation.
Much like some of the new 'Facebook' app/games that are starting to become popular, (especially with the addition of the iPhone and its cross-over apps) games such as 'Mafia Wars' have really captured the attention of the new breed of casual gamer. (Feel free to jump in if you are familiar with this game, as I would love to hear your opinions).
In many ways 'Mafia Wars' is meta-gameplay without any core gameplay. In this respect the plan with our project is to create a gameplay experience that can be integrated with some kind of cross over meta-game portal like this.
So going back to races and enemies in general, we plan on creating several sets that allow some dynamic mission content to be created based on meta-game match statistics, that give a good deal of variation to create longevity of interest with the title and continued challenge for the gamer.
Combined with an inteligent dynamic-dungeon system, we should be able to create a game where we, the developer, can release new themes, items and rares, along with big boss fights and so on to hopefully continue/increase the effective shelf life of the product.
I am also very aware that as a new startup developer with limited time and resource that our target title must be as production light as possible and this is why dynamic content to us is a key consideration.
It's also why I am focusing on the core-gameplay and building one race of enemies that covers the broadest spectrum of these elements.
On a final note:
I really would love to hear ideas about other races, reference material, ideas for cool game-mechanics and anything associated with it really. I am also inviting discussion about meta-game play and ways indie developers like us, might take advantage of this new boom.
TIA for your interest and feedback
