It is worth mentioning that all the best strategy games are PC-only. From the entire Total War series, to Crusader Kings II (pure genius), King's Bounty series, Heroes of Might and Magic, Sports Management games like Football Manager, 4x games like Sins of a Solar Empire, Galactic Civilizations II, and Frozen Synapse (now available for Android though). Of course there are also many plain games such as Torchlight II, Gunpoint and others. Still, I think the area where game selection on the PC outweighs all consoles by 10 to 1 at least, is strategy games.
