I understand where Riot is coming from ryuu, don't get me wrong, I just don't agree with it. Game Lore should be a part of the game itself - not separate from it. And if it's not in the game (which is the part of league that really matters) then the lore might as well not exist.
That's my take on it though, feel free to disagree.
it's not like lore won't have a place in league. like it's cooler playing ezreal, super famous explorer dude instead of ezreal, anime guy. or like, riven, the noxus exile seeking her own path vs riven, sad girl w/ sword
but MOBAs just suck for progressing stories. the most you can do would be like a soldier vs demoman kind of event like tf2 did
Also, what are you implying.
riot has stated that they want to make more games
they even pointed out that they're company name is riot gameS with an s implying plural
they're hiring a bunch of people from different disciplines of game design, likely to start making new league related games that will do things to progress the lore. or maybe even movies or books or who knows what. they have a lot of people rn who can put out all sorts of stuff
you are now manually imagining a jak and daxter type game starring ezreal in piltover where ezreal upgrades his glove to get a bunch of different weapons and abilities
you are now manually imagining a tenchu/metal gear type game starring the kinkou team and/or zed
you are now manually imagining dynasty warriors with garen and darius and so on
and these are just knock-off games from the top of my head, so who knows what they might create in the future
