Overall, I do not believe there has been another similar event; solely because many of the events before and since then have placed the motive for winning and grinding exclusively on the individual player. As opposed to this event, which had players coming together for one common goal. I am not confident that the aura around the game will be replicated unless they bring back the Houses or another similar concept. One event that had one of the most significant impacts on the LOL fandom and game as a whole was the Bilgewater Event back in 2015. This event brought so much to the game, similarly to the 2019 Mid-Seasons Trials. It had so much Lore and brought in new maps, skins, items, everything!
