I find any list of this type to be very fluid, listing the top twenty games of all time objectively would be impossible.
What I’ve done here is to list the games that had the biggest impact on me across a broad spectrum of genres as possible and always come to mind during these types of conversations.
I actually wrote out this list a couple of weeks ago and then returned to it later to see if it still felt ‘right’ and it did, so I stuck with it.
Next month, who knows? It could be a different story.
