Time Travel Game Mode/Event/Client?
Just an idea I had early today. But why not start up a game mode that's essentially a "Time Travel" version of League of Legends? Allowing players to play the Old Version of each champion or the Current Version of each champion, as well as access Discontinued Items and Current Items.
Obviously not EVERY iteration of champs/items (otherwise we would be looking at a smooth 50 different Ryze's to pick from :P), but allowing players to pick their first iteration (Launch Day maybe, or more likely the first patch in which they were "balanced" after their launch) or their latest iteration.
I think I read something about this in the past where a Riot Employee said that it was a pretty unique/decent idea, but that the old character game files are no longer present? (not 100% certain on that). I know it would be a super huge mess to try and add them back in. But you could potentially choose a handful of champions to utilize for this (instead of ALL champions). For instance, obviously, Current Gnar vs Old Gnar wouldn't be TOO different because the kits are effectively the same. However, Current Akali vs Old Akali would be a bit more different since she (soon to be) has been reworked. That would definitely cut down the messiness of it, and you could still pick and choose which you actually use from that roster.
With the roster selected, you could then work to give them some sort of "Time Travel" themed skins, and voila! Event Success!
An alternative would be to setup a secondary client with the older files that pulls information from the current client's database to create the setup of Old vs Current.
Just a thought that came to mind, you do you Riot. You do you. [slayer-jinx-wink] [slayer-pantheon-thumbs]
