Steam

This is an excellent point. The availability of games.

On PC, you can play pretty much every game ever, with varying degrees of legality, whether directly, or indirectly using an emulator, with the only exception to this being very modern titles on consoles which do not have an emulator for PC yet, or that are still locked in a bullshit exclusivity deal.

Meanwhile, PS/XBox is limited to whatever Sony/Microsoft deems appropriate to have on their console.

On console you live and die by someone else's rules, on PC, the sky is the limit.
