League of Legends used to used to be on Steam until it started to get big and DOTA 2 began to compete with it.
Not exactly. It was on Steam until Valve implemented support for free-to-play titles and would have had to migrate to the policies of the time (i.e. DLC to be sold on the Steam Store and microtransactions to use Steam Wallet) as it wasn't actually a pay-to-play game. It's probably also worth mentioning that the game wasn't available worldwide, only on select European stores.
Even if you negate the others, THAT'S the Big One right there.
I disagree. I mean, EA taking Crysis 2 and Dragon Age 2 off Steam to prop up Origin and League of Legends' limited availability becoming worldwide
unavailability both happened more than half a decade ago now -- there's precedent, sure, but not anything remotely resembling a trend. Additionally, it's not uncommon for F2P titles to forgo Steam until there's a need for a last-ditch effort to increase monthly active users, as we've seen most recently with WildStar. They're separate beasts to pay-to-play games.
Also as I do recall, there's been a LOT of whispers concerning a Bethesda.Net launcher. I'm not saying the transition will happen this year for any already announced games, but foresight is oft 0/0. Everyone thought Battlefield 3 would be a Steamworks game until it wasn't.
There has been
speculation that's what Bethesda has been moving towards, but that's all it is -- speculation. People suspected that WB Play would mark WB's push towards following EA's dusty footsteps, too, but that launched almost two years ago now and firmly remains as some sort of glorified newsletter service a la the also-years-old Square Enix Account system. Also, just to be perfectly clear, I didn't say that the two examples I gave were proof that a shift away from Steam for Acti and Bethesda
wouldn't happen, just that it's
not happening. Could B.net and, uh, B.net be retooled for that purpose? Absolutely. Is there any reason to believe that's on the cards, though? None whatsoever beyond "EA did something similar in 2011".
Also I'm pretty sure that Battle.Net as a launcher wasn't until after Steam was a thing. Wasn't Battle.Net ingame-only until they needed a more sophisticated patching system for WoW?
It wasn't always a digital distribution service, true. But becoming a DD service was a natural progression from the foundation Blizzard had built over the years using B.net as an MP middle-man for its games. I think there's a distinction to make between "A service can be successful enough without Steam" and "A service can be just as successful without Steam". As I theorised in my previous post, Origin points to the former but not the latter, which I would presume is why nobody -- most notably Ubisoft given that Uplay turns seven later this year -- has followed in EA's footsteps (again, though, with the quasi-exception of Microsoft -- I'd liken the WinStore push more as an attempt to replicate Battle.net rather than Origin given that Microsoft previously wasn't in the business of selling its AAA games on Steam).
