I have 90%+ of my 348 game library installed on my PC (~1.5TB of games, not including uPlay, Origin or GOG games). I installed them all late last year as I have the intention of completing as many as possible this year, 100% where possible with the main exceptions being multiplayer games and SP games that have dead multiplayer parts that have achievements linked to them.
It's a hobby... Or a problem... Hoblem?
