I've been looking around the store and most feel quite old either from the pre-3D era or very early 3D which make them look like non-cubic Minecraft. Is there anything new-ish and AAA level?

Plenty of stuff, in fact (not all of them are "new", but certainly looks like (are?) AAA games):

And much, much more (those are only some examples)

Old games rule!

Two reasons:

The store started off as Good Old Games, with the intention of releasing old games that were hard to get and tweaking them so they would run on modern systems.

When the store expanded into releasing new games as well (which GOG needed to do for continuous income), many publishers of 'new-ish and AAA level' games, are afraid to put their games on a DRM-free store as they (falsely, I think) believe that putting DRM on their games will get them more sales (they get pirated otherwise, is their reasoning) and they only release their older titles here, that already had many sales but will get a second life because of people wanting to get them without DRM. Proving release without DRM is a selling point, therefore making their first argument moot, moreso because games get pirated anyway, despite DRM.

of course, if you're not a fan of turn based games, then perhaps the cutting edge rpg Akalabeth might be more your thing?

You have a join date of 5 years ago. Are you seriously saying you don't know what this site is all about?

You should definitely check Nexus: The Jupiter Incident out .

Cosmo's Cosmic Adventure isn't new? Have they stopped selling LaserDisc yet?

I remember the first time I played Baldur's Gate like it was last week. Surely the game is no more than a few years old.

Maybe you are just too young ?.

Almost as if the person using the account now might not be the same person who signed up for it originally.

I don't know how to say this... but you have been afflicted with the Curse of Late Birth.

He's chronologically challenged.

Assuming s/he has the hardware required to run this cutting edge program....
