To clarify about Tomb Raider:
* If I follow your instructions and check Account Details -> Licenses and product key activations, the title listed there is just "Shadow of the Tomb Raider", no mention of "Definitive Edition", no DLCs.
* Humble advertises the Game as "Shadow of the Tomb Raider", "Definitive Edition" only appears in the small print that at the same time states that it will only include the base game, which seems absurd, but I think this confusion is caused by the following:
* On Steam the page for the base edition was renamed "Shadow of the Tomb Raider: Definitive Edition". You can't buy the game on this page anymore, you can just click on a "Shadow of the Tomb Raider: Definitive Edition"
bundle, which according to Steam contains Deluxe Extras, Croft Edition Extras, Definitive Upgrade and the base game, but since they renamed the page of the base game to "Shadow of the Tomb Raider: Definitive Edition", the base game item in the bundle is shown as "Shadow of the Tomb Raider: Definitive Edition" now, which creates the paradox of the "Shadow of the Tomb Raider: Definitive Edition" bundle supposedly consisting of "Shadow of the Tomb Raider: Definitive Edition" + DLCs, where "Shadow of the Tomb Raider: Definitive Edition" actually stands for the base game only. So this mess is not just Humble's fault, but on Steam or the publisher as well. It's actually a bit less confusing on Humble, because they don't use "Definition Edition" in the game's thumbnail. So I think Humble isn't guilty of false advertising that much, they're just a little confused themselves.
* That being said, it's still typical and a bit lame of Humble to just offer the base game (and I wouldn't pay 26 EUR for the DLCs even if I got the main game for free). Also, it seems you can't buy items of the "Shadow of the Tomb Raider: Definitive Edition" bundle individually, so e.g. no "Definitive Upgrade" without "Croft Edition" or "Deluxe Extras", it's either all or nothing. The three extra content items still have their individual store pages but no individual buy buttons.
I'm going to pause this month, and if future Choice bundles don't get better, I might even cancel the Classic plan. (To be fair, the first month is very heavy on Strategy games - 6 out of 10 -, and there is Racing and Simulation on top of it, which probably explains why I find it so underwhelming, personally, apart from the Tomb Raider disappointment. I still have a tiny little bit of hope that future bundles might cater more to my own preferences or at least offer more variety in genres.)
