The complete saga is 111 MB in size, while even the first game is 158 MB in size, the second one is 226 and so on.
I really don't get it, how is that possible, that the COMPLETE saga is significantly smaller in size, than any of the games individually? Even the price doesn't make sense.
If this is a complete ("Having all necessary or normal parts, components, or steps; entire.") why it is so cheap, and smaller, compared to the individual games?

Does It means, this "complete" saga doesn't contain all the goodies that are part of the games, when someone buys them individually?

It's because the individual games are actually remakes of the games from the complete saga, with a lot of changes made.

Interestingly enough, the original Avernum games are, themselves, remakes of the old Exile games.

If you don't know which one to get, there are demos available.

(Saves from the demo should work on the full version.)

I directly marked my question, and as it said: "Mark as "question / problem" (special category of "help me" topics that encourages others to answer and earn reputation points for solving your question / problem; offtopic chatter is forbidden."

I done this to encourage people to strictly post about the exact question that I asked, because I really sick of reading through hundreds and hundreds of useless posts, wastes hours looking for answers, just to find a tiny bit of information that maybe have something to do with what I looking for.
I done this to avoid posts like yours. Sorry, but I didin't asked anything like that, what you posted about. I nowhere asked about the origination of the game: I didn't asked about which game is a remake of which other game, or about demos of the games.
I asked about (because I realised the huge file size and price differrence) what other things, like the goodies, are come with the individual game which isn't part of the saga.
Or somthing like that, becase it just bugs me so much, how is that possible that 6 games bundled together is smaller than even 1 game. I need indepth, technical explanation about what comes with the individual games, and what comes wih the saga, that explains the huge file size difference. Especially about the goodies, that what I aseked.

Regardless that I can't accept your post as an aswer, thanks fot the info that the saga contains outdated version of the games and that the individual games are improved, later versions (hence the much higher price) of the games. Or whatever you mean by that meaningless "with a lot of changes"... At least it is a bit more information about the games.

Still, I like to know about what goodies the games and the saga contains exactly, so that I can compare them to eachother. If the file size and price difference not just because of the goodies, I like to get more technical explanation what are the difference that makes that huge size difference.

Thanks.

As I said, it's because the individual games are remakes, and as such, the games themselves are significantly bigger than the "originals" that are contained in the "complete saga". To put it another way, the "individual games" are not the same games as those thar are in the collection. (In other words, the fact that the :"individual games" are remakes is 100% relevant.)

Older games tend to be much smaller than newer games, as newer games generally are significantly bigger. As technology progresses, storage capacity increases, bandwidth increases, and as a result, games get bigger to take advantage of said improvements.

Remember, there was a time when computer games were distributed on floppy disks, which could typically store only 1.44 megabytes (or less); those days have passed, and as a result, games got bigger in order to take advantage of the extra space.

Thanks.
Now I think I didn't really worried about the goodies, because of those mechanics how changed in the reamke.
I really doesn't like it. I playing PC RPG games since I had my first, PC and that was in the 90's.
And all that things you mentioned (that are either removed or changed), those what you refer as 'old and clunky mechanics' are somewhat a 'standard-rpg-experience' to me. Like that you don't have 'unlimited' storage space, so you have to decide what you grab (or go back and forth if you want to pick up everything). Manually identificating the loot is also a normal thing to me.
Even if the garphics are improved in the remake, I think I like the original old-school mechanics better.
Regardless the graphics, all those changes just makes the games "dumber" to my taste, I prefer more 'hardcore' RPG experience with all their limitiations. So this is really good to know.

Tho' I really wanted to know more details about the goodies, I think this is the most helpful post, that explains what really are the changes. So people can choose they want better graphics, but somewaht easier mechanics, or the don't care much about the graphics but like to play the game in the oldschools way, as it is originally come out.

well, if people wanted the truly original experience they'd have to play the exile games, but those are even more primitive than the original avernum (this is getting confusing)
