Hi Ixxxl, I like your suggestion. However, although possibly more realistically achievable in a game, considering we have something of the order of several hundred to several thousand worlds possibly at stake, it still leads to repetition in maps which represent different planets.
This is why I suggest partly
procedural generation of generic maps with set environment modifiers.
For example, there are two jungle worlds represented within the meta game. These are, for most intents and purposes, different planets.
The first orbits a G star, and has light fog. There's a normal yellow skybox.
The second orbits a B star, has heavy storms, fog and has a blue skybox.
The generic map itself is relatively identical. There's an algorithm to generate contours for the map, using a procedurally generated alpha map on a rather flat terrain. Tree and shrub density can also be procedurally generated for each world.
When you play it, they look vastly different - different elevations at different locations, different weather conditions, gravity, trees, etc.
Because it's procedurally generated the algorithm is fixed as is the inputs - everytime you return to the map of this world it'll look the same, but go to another jungle world and it'll look different, go to another and it'll look different again. The only art assets you need are various trees, shrubs, rocks, grass textures, etc. Rather than hand place trees in each map, you could generate 10 jungle maps on the fly that look and play differently, and save data space and modelling work. But these aren't random maps, you won't suddenly find yourself in an inhospitable moon-like surface when revisiting the same planet.
However, I have no idea how CryEngine 3 maps work. From what I recall of some youtube videos it's quite standard fare with maps and placing of objects, so I'm not sure whether integrating procedurally generated maps becomes a worthwhile endeavour. I would like to see variation between the maps though in some form or another, unless we all somehow end up fighting for control over 8 planets or something.
