Telika: The more DLCs a game has, the bigger the discount. On the base game, of course.
Hey look. 5% of the game is FREE !! Woot.
amok: *shrug* the game has a start, middle and end, with lots of content and it is perfectly playable without any of the extra fluff.
I don't know. I bought it long ago, heavily discounted. Haven't played it yet, because "oooh for the real experience you totally need THIS and THAT expansion, which adds THAT and THIS dimension" [don't even quite remember which ones it was, religions or stuff like that].
And my point is more general. Fragmenting a game into DLCs is, I noticed it on gog aswell, a great way to look like you're offering generous discounts (like 75% on the base game) while keeping the discount minimal on the DLCs. It looks more like creepy fish hook investments, aimed to facilitate further expenses. It's annoying to look at game discounts and having to ask "wait, which portion of the game is discounted how much now". Such giveaways are an extreme case of this.
I wonder how many people, amongst those who are getting it for free, will (or are expected to) play it for free.
