MysterD: That's the thing w/ newer games - they often use proprietary stuff in each version; i.e. Steam has all its Steamworks stuff; and GOG has all of its Galaxy stuff.
eiii: It's not only with newer games, even older games get affected. It's the people which cry for shop-specific online features.
MysterD: This ain't the old days, when bringing a game to GOG and Steam was easy, as there wasn't GOG Features and GOG Steamworks features. Didn't have to worry about Fallout 1 on GOG or Steam, as things like Achievements weren't even a thing back then; and it's not like the game got updated on Steam w/ Achievements added either.
eiii: Achievements itself never have been a problem,
online-achievements are the problem. The good old days when people had a life and did not need online-achievements to brag about...
Proprietary/shop-specific online features:
Also true. I remember when most multiplayer games were using GameSpy - and well, that service is gone. Some games got no new Multiplayer suite; some got moved over to Steamworks; etc etc.
Makes me wish for more games to allow for LAN/TCP-IP support, like in the old days.
Also, I do wish a lot of these skirmish MP's....got re-worked into offline modes w/ bots. Or some MMO's, which are very single-player friendly like The Secret World/Secret World Legends - got re-worked to also work as an offline game.
Achievements:
IIRC, even games like Divinity 2, that had their own Achievement section built directly right into the game. We need more of THAT again. And then, once the game realizes you got the Achievements offline - and then say uploads it to Steam or GOG Galaxy, if it can connect; and if it can't connect to those online servers, it will try again to connect some other time and just let you keep playing.
We've also already got enough madness going on w/ PS3/4/Vita preservation and now w/ the chance that PS4 games in the future, if PSN goes down/gets its plug pulled and it can't connect to PSN - well, Trophies are what can cause your old games to not work. See this here on YongYea about this new mess -
https://youtu.be/hNTOLRLUqWw I'm not an Achievement-Hunter and all - but I do think it's cool when I get one and a pop-up says that I achieved something. Most of the time, I ain't hunting - I'm just playing the game, old-school style: just to play-through.
