i dont agree totally with the more tanks wins in ra2, at all
ive won games against really good players where i was attacked with 10 prisms, vs just 3 apocs, but i managed to crush his attack. ok, that sort of thing is possible mostly in a long game, that lasts an hour at least. in another game, which i lost eventually, i killed 5 prism tanks with a lone apoc and boris, defending my base and prolonging the battle a little more
u obviuosly havent ever faced similar problems in starcraft of more the merrier, but i assure u, it is easily accomplished, not on the ground, but in the air. nothing stands up to the protoss anyways, they r just too powerful, scouts n carriers in the air, reavers and dark templars on the ground.
