Hm...there is a lot of that..
I would like a collector's edition of
Tomb Raider, that would come with a statue or figma of Lara.
If it was a figma, she would have changeable faces and accessories, such as her bow and guns.
Also there would be a big, A4, hardcover artbook with lots and lots of concept arts, interviews and character design and not only for the newest Tom Raider, but also bits of data from the previous games.
And, of course, you can't forget the soundtrack, you need a soundtrack for every new Tomb Raider game!
The whole thing would be packed in something in-game related (like Lara's backpack, or a treasure chest, or at least well designed box)
The second game I'd like to have collector's edition of is
FF Versus XIII (or at least I hope it's finally getting released this year)
It would be something similiar to Tomb Raider, the game would come with a posable figma of Noctis with accesories and a big artbook with game and character design, informations, documentary and so on.
The game will probably have limited edition soundtrack anyway, which I'm gonna buy, so that one isn't really necessary, but a selection CD wouldn't hurt I guess.
It could also come with something like Noctis's blade, which would work as a letter opener or a big keychain.
Also, also they could make a short, about 20-40 min OVA that would serve as a prologue to the game (something like AC lineage, but an anime), and it would be packed on a seperate Blue-ray/DVD disc. Alternatively it could be a light novel or a manga (but not the shitty 20pg booklet, like the EP1 of FFXIII-2, but a full 200pg volume).
The best possible outcome would be both ova+manga/LN of course.
The next thing is
AC3, but I trust Ubi on this one, they always manage to come up with something decent.
I just hope the main dish is not going to be "an updated encyclopedia", lol.
A figure of Desmond would be nice though (as long as it's going to look more like the ones from AC1 and AC2, not those mass-produced-buy-seperately crappy figures they sell recently).
For
Persona Mayonaka Arena I would like...a manga/or artbook and a set of cute nendoroids!
Also, it would come in a box, that would imitate a TV
For
Dead or Alive 5...Ayane's flowery message-kunai (you know, those things she always throws to Ryu in Ninja Gaiden) and a figma of Ayane (what? she is my favourite character). Or alternatively a figurine of both Kasumi and Ayane so it's more fair, lol.
And other things, like soundtrack, artbook etc, wouldn't hurt too, of course.
There is a bunch of Japanese games I won't mention, because generally Japanese developers are more creative when it comes to collector's edition, so I'm in most cases happy with them.
Also, about my dreamlike games (meaning they don't exist, as far as I know at least)
I would like a new Fatal Frame, for a home console, with a replica of camera obscura.
And any Umineko related game, that would come with a figma/statue of Bern and/or Lambda.
Basically, I'm a sucker for figmas and big artbooks (I really hate those shitty A5 horizontal ones)
But geez, OP. Now I'm going to dissapoint myself, since no way in hell are developers gonna make my wishes come true, even halfway
