[quote]Halo, hands down. The Precursors can solo DW and 40K[/quote] Yea, you have no idea what you're talking about. Necrons led by the C'Tan would slaughter ALL of them. It took the Gods themselves just to [b]STALL[/b] their power. And if they completed the Obelisk at the Cadian gate it would wipe them as well. The Tyranids would either counter, or ensure the mutual destruction of the Flood. The Empire would annihilate the human elements relatively easily. The Eldar remnants would massacre the Covenant if the decided to bloody their hands with such ignorant filth. And if they didn't bother someone else would mop up the mess. That isn't even mentioning The Old Ones, Tau, Orks, Dark Eldar, or the forces of Chaos. And The Old Ones would probably wipe them all by themselves as well.
