There are now a few digital distribution platforms for content delivery. Its hard to keep track of them so I though I would do a list of the ones I know about and see if there are any more out there,
Its the biggest with the most games. Usually when you buy a game it will come with a steam key. Regular sales and a lot of hentai and absolute dross dominate the front page and leads to a lot of games being hidden.
Originally launched as a place for Good Old Games, it morphed into a steam rival a number of years ago. It offers a curated selection of games, sometimes overly selective, which makes for a smaller selection but it does offer DRM-free versions of many games.
A indie centered site with lots of odd and weird experiments. Devs can set the share with itch.io so usually the devs get a greater payout from itch.io.
EA’s client, the only place to get the newest EA games such as Battlefield, it also has a host of indie and 3rd party games but they play second fiddle to EAs own games on the store pages. Offers Origin Access Premier with a €99 a year price tag that lets you play all EA games up to 10 days before launch.
Home of Ubisofts games such as Far Cry and Assassin’s Creed, these can be bought in some of the other clients but you need a uplay client and account to play them.
Home of Blizzard, Overwatch and Diablo and Activision, Call of Duty and Destiny 2. The newest Call of Duty is exclusive to the platform on PC so expect future games to be exclusive too.
Launched a number of years ago but fully embraced this year with the launch of Fallout 76, expect all new bethesda games to launch on it.
Home of paradox games. Has been around for a little bit, I expect them to keep releasing on steam and offering the launcher as a alternative download.
For Rockstar games, it lets you slowly download their monstrous game sizes like LA Noire, GTA V or Max Payne 3. If you buy the game from pretty much anywhere but Steam you will more than likely have to use Rockstar Social Club and hope that it works for you. Now has a launcher with cloud saves and updates for games
Green Man have some games on Playfire, which used to be a seperate community and is now apart of Green Man Gaming. Only for some games though so read the page.
The chat app launched a games store this year with a Origin Access option of a monthly fee to play a large collection of games, games tend to be indie or small publisher based with some exclusive launches of games before Steam release.
Indie focus with a decent selection of games. The games tend to be more well known games than itch.io but still a good chance of seeing something new.
The streaming giant launch a client to watch streams from your desktop and they give away games and ingame fluff to Twitch Prime members. At the moment there is no store to buy games in the Twitch client so the only way to get games is to have Twitch Prime by subbing monthly or to link your Amazon Prime account to Twitch
The latest to launch a store, already had a client for the massively popular Fortnite. Has exclusive launches and a real chance a getting a piece of the Steam pie with decent Dev share and offering free games every two weeks.
Windows Store - Native to Windows 10
Microsoft own brand in built store. Home to Win 10 exclusives Sea of Thieves(yes it was released on PC) State of Decay 2(again yes it is out) and Forza Horizon 4 one of the best games of the year in RPS calendar. Its ok if you know what you want and go in and download it but as a store front its awful.
Not a mob about ethicsless women but one of the first game stores to really take off in the olden days. No launcher but does downloads and manual updates with their own DRM thingy.
Humble are the bundle top dogs, they tend to give a key to one of the store above for game, tends to be Steam, but they do offer DRM-free downloads of games and for monthly subs a collection of decent indies to download.
Home to games built for the Oculus Rift headset with some exclusives.
Home to games built for the Vive VR headset
Offer a selection of games direct download but as with GamersGate and Humble most come with keys for a service such as Steam.
Amazon offer a limited download section most come with a key and the site is heavily region locked, you must have UK address to buy from the UK site.
I think that is all of the platforms or am I missing an obvious one?
