Mal so ganz nebenbei, was haltet ihr davon?

Alright, this is a compromise between the original Tiberium by Westwood and the new one by MIT.

There are two major stages of Tiberium.
At the very beginning, the pod will leech minerals from the ground with real roots and store them in a Tiberium crystal. More concentrated minerals will cause blue crystals. By getting near to a tree, the Tiberium will mutate it to a blossom tree with bulbs, spreading tiberian spores. (Riparius)
The Tiberium (green and blue) will keep on growing and spreading. By reaching a certainly size or the ground doesn't contain anymore minerals to leech, the pod will cause the crystal to change its behavior form. The Tiberium crystal will begin to collect atoms by adding them to itself. This will cause, the pod being crystallized and everything else, the Tiberium crystal will touch (even nearby blossom trees). The blue Tiberium will first expand to a Vinifera, by spreading normal blue Tiberium (belonging to the first stage) and slowly growing to a Cruentus, spreading Viniferas. Aboreus can be used to describe the green Tiberium of the second stage. This Aboreus is limitless in growing bigger and bigger (compare pics of red zones), but the blue one will stop growing bigger by reaching the Cruentus class.
Being around with Tiberium of the first stage is not as dangerous as being around with Tiberium of the second stage. You can touch first-stage- crystals by having no fear being crystallized. This sort is very easy to harvest, i don't know to harvest the second stage. Blue Tiberium of the first stage is explosive due to its high concentration of minerals. Vinifera and Cruentus are not that explosive, but very sensitively. By shooting at Cruentus, they will "split up" and shower crystals / themself around the landscape up to 600 metres. The first stage Tiberium in general will cause mutations (Fiends, Visceroids, Floater, ...) and the second stage will cause crystallations (bridges, metals, humvess, ...).
The second stage is caused by GDI's tries with the Tacitus to stop the Tiberium between the years 2030 and 2047.

Basically, you can say
first stage = modified original Tiberium incl. Riparius, green and blue Tiberium
second stage = modified new Tiberium incl. Vinifera, Cruentus and Aboreus
