A proper Sacred 3 perhaps?

I would really like a proper sequel to Gothic 3, assuming Piranha Bytes went back to the Gothic/Risen 1 formula instead of the path they went to with Risen 2/3.

I would also LOVE a sequel to Vampire The Masquerade: Bloodlines. Legal issues aside (does White Wolf even allow new media based on the Old World of Darkness anymore?), Troika Games is long gone and they're the one single developer I would trust to truly do the game and the universe justice. There are devs who could probably do a decent job sure, somebody like Rocksteady (Arkham Knight PC blunder aside), Ice-pick Lodge, Larian Studios and Obsidian come to mind, but I would really hate to see Bioware, Bethesda or any other devs be the one to work on it.

The sequels I still am wishing for ?

Bulletstorm 2
Kotor 3
Half life 3 (no, I do not believe in it and I never expect it at E3 but, hey, it is a wish, right ?)
Beyond Good and Evil 2
New Rayman
Age of Empire IV
Warcraft IV
Prince of Persia
Silent Hills (or a new Silent Hill, whatever)
Dissidia sequel
Zoo Tycoon 3

Surely others, but...right now not thinking about them....

(didn't mention the games that are less than a year old)

they totally abandoned prince of persia with their assassin creed sequels :(

prince of persia 2008 (reinterpretation)
prince of persia forgotten sands -> an attempt to reboot series?!

2008 version was quite good story-wise

Didn't really touch me, was ok. Though I can see why some would like it.

The new Thief wasn't that bad actually. I played it on the Expert difficulty and it played very much like old Thief, just SLIGHTLY more linear.

Overall I really enjoyed it, and would actually recommend it. Their biggest downfall was not involving Russell. If he had done some monologue or something at the beginning, then I'm positive it would not have gotten the hate that it did.

I think the change of esthetic also played a role. The previous Thief had this unique esthetic whereas the Thief "reboot" was more....classical.... Well, didn't stop me from liking it despite the "hate" too.

The typical aesthetic certainly hurt them, but overall the gameplay was solid, and it didn't detract too much. I haven't tried any of the DLC. It kind of sucks how with all of these new games the DLCs are never discounted.

Most DLCs are way too expensive to begin with (for what they have to offer).

I'd like more of the Secret Files adventure game series. They're relaxing but not insultingly easy. If you like McGyver style inventory puzzles, you'll get your money's worth here. The first one (Tunguska) is quite underrated and should be in any point & clicker's library, the sequels are so-so but fun enough that I bought them all and would buy more.

The Dr. Brain games were excellent. More should be made. Or, heck, just release the old ones here on GOG, it's not like logic and physics have changed enough to warrant a whole new game.
