I was reading some of the old sb threads and found a versus that i thought was interesting to see how it went away from sb.
on a planet in a neutral area two alien armies are diverted when travelling through there ftl dimesnions and forced out onto an alien world. both are equipped to maintian their forces with supplies and infantry reinforcements but as is normal they can't build stuff on the planet
both forces are of equal size with sort of the same type of troops but only ground troops but they can have fighters and bombers and dropship type things
a dark presence compels them to fight each other and after several weeks of scouting each other they begin to fight.
the protoss are from sc2 times so they have the soldiers they might have then inc dark ones and the eldar are from biel-tan for options replace them with different craftworlds like iyanden and ulthwe
who wins
