few decades i believe is asking quite a bit.. but even a broken and shell of game as SWG has lasted 7 i believe.. so maybe it isnt so hard to believe.. 500 worlds tho?
I guess i failed in my numbers.. 133 zones total for the major planets of SWTOR; this is excluding operations, flashpoints, warzones, smaller implemented planets and space zones (since we dont actually have the information since they havent released it yet). WOW has a total of 200 zones via continents,dgs,bgs,arena and raids. Keep in mind what took wow 6 years to do SWTOR is doing in origin(launch).
numbers for was based on the lowest amount of zones[7] per planet compared to that of wow in all its expansion.
this does not include the size of wows zones vs the size of the planet and/or levels the planet contains via taris has multiple
levels(upper city, lower city). So to determine the actual size of SWTOR is impossible at this point. Darth Hater has said
it would take literally a half and hour to travel from one corner of tatt to the other. half and hour of hopping on your speeder
and punchin it to the other side.
