There are Expansion Packs sold on gog.com and Steam. Well the Expansion Packs are bundled on gog.com.

Oh sure. You go ahead and call them that. I'll just stick to DownLoadable Content :-P

Train simulator is a rather poor example, since it is essentially a base platform (the game) to plug in the specific parts (DLCs) you want. You're not meant to purchase everything (unless, of course, that's your fetish), but the parts that matter to you.

Logical fallacy on Ubisoft's part. The lack of 'resistance' (interesting term) does not indicate a waning view against DLC and microtransactions. It does indicate though that the many people who do not support such practices don't interact with companies like Ubisoft about it anymore - they just stay away and avoid them and their products altogether.

Expansion Packs add a lot of new stuff DownLoadable Content (DLC) adds only like 5 maps or 1 new gun skin or 1 new clothing skin or 10 new quests or 10 new vehicles, Stuff like that is DLC's.

Several of us consider DLC to be any add-on you download, regardless of size, and even that's more narrow than the literal meaning of the phrase.

Personally, I use the term "add-on" in order to include stuff that comes on disc as well.

Well I believe it's wrong to call expansion packs DLC's when expansion packs expand the main video game a whole lot. I just don't see why some people call expansion packs add-ons. Sure it adds content to the main video game but the expansion packs add a whole lot of content to the main video games. While add-ons or DLC's just ad stuff like 1 new gun skin or 5 new gun skins or 10 new maps, etc. Stuff like that.

You mean like Deeper Dungeons DLC for Dungeon Keeper which added 15 new price for the low price of like 30 bucks? Oh, right. No, there's absolutely no difference whatsoever. You're just calling DLC that you like 'Expansion pack'.

Those are, however, completely arbitrary definitions, and liable to change from person to person, there's nothing in the terms themselves that define how much or little should be in the package for it to be called one thing or another. The only thing "downloadable content" really says is that it is acquired via download, while "expansion" and "add-on" really say the same thing, they expand or add to the game in some way (no telling how much).

Huh? No I am not talking about that.

This is what I classify as expansion packs.

#1. Now in order for a Expansion Pack to be called a Expansion Pack if the video game is a open world singleplayer video game that you can constantly explore like The Elder Scrolls video games it has to have over or at least 30+ new types of armor (medieval or modern if the video game is a medieval video game or if the video game is a modern video game), over or at least 30+ new types of clothing (medieval or modern if the video game is a medieval video game or if the video game is a modern video game), new land that is the same size as the original video game itself or bigger than the original video game, over or at least 100+ NPC's, over or at least 30+ new types of weapons ( medieval or modern if the video game is medieval medieval weapons if the video game is modern modern weapons) and at least over 50+ campaigns, missions, stories, quests or whatever you wanna call them if the video game is medieval or modern.

#2. Another Expansion Pack is if the video game is a open world singelpalyer and multiplayer video game that you can constantly explore then same thing as #1.

#3 Another Expansion Pack is if the video game is not a open world video game they you can constantly explore but still singleplayer instead of having constantly explorable land or both singleplayer and multiplayer and you have levels or maps that when you beat a campaign, mission, story, quest, whatever you go onto the next level, map, whatever this Expansion Pack needs to have the Expansion Pack in either 2 ways requires you to have the original video game itself installed in order to play and once you install the Expansion Pack it takes you to a whole new menu and stuff like that for anyone who played Call of Duty and Call of Duty: United Offensive that's how I want the Expansion Packs or the second way the Expansion Pack can be is you don't need the original video game itself to play you just install the Expansion Pack but it still needs to have a whole new menu if anyone played Far Cry 3 and Far Cry 3 Blood Dragon you will know what I am talking about and it still needs over or at least 30+ new types of armor (medieval or modern if the video game is a medieval video game or if the video game is a modern video game), over or at least 30+ new types of clothing (medieval or modern if the video game is a medieval video game or if the video game is a modern video game), over or at least 20+ new maps, over or at least 100+ NPC's, over or at least 30+ new types of weapons ( medieval or modern if the video game is medieval medieval weapons if the video game is modern modern weapons) and at least over 50+ campaigns, missions, stories, quests or whatever you wanna call them if the video game is medieval or modern.

Just like #1 new everything. There can be some vanilla stuff as an exception but there has to be lots of new stuff as well. I will gladly pay $20 dollars (USD), $30 dollars (USD), $40 dollars (USD) or even $50 dollars (USD) I don't ever want to pay $60 dollars (USD) for video games ever again or even $51 dollars (US)D if the video game is $50 dollars (USD) + $1 dollar (USD) because of tax or 1 cent because of tax then I will pay it that way and since I live in California there is sales tax so the video game will cost a few extra dollars (USD).

Collector's Editions are flooding the market. You have about 12 variations of that for Assassin's Creed.
What you are talking about are Complete/Gold/Ultimate/Premium/Whatever Editions.

You have just excluded vast majority of expansion packs (as in the official title being an expansion pack) ever released from being expansion packs.

I can also guarantee you that The Witcher 3 expansion packs will not meet those requirements.

Typical part of the Steam generation :P

I described how expansion packs should be.

All I can say is we will argue about this for years to come I have been arguing about expansion packs vs DLC's vs add-ons since 2006.

amazingly I can't disagree with you
