wow that looks awesome. i want to have all those pieces :D
GIANT CHESS
Couldn't get to the link to see what you are referring to, but I have 3D chess in my loft, which is three fullsized boards stacked vertically, and the middle board pieces have 3D capabilities. The knight equivalents move 3:2:1 in 3 dimensions, as opposed to the usual 2:1, and they're a nightmare to track. I also have a threeway set, in which 3 players have a standard set of pieces each, and the board has three ordinary halves, for the pieces to start in, and then this all morphs together in the centre. A photo would help if I could sort one, wouldn't it?
Needless to say, neither have been played a great deal, and both are mindbending. As if chess wasn't complicated enough already!
The link worked at the second attempt, and I feel a headache coming on!

Something happened during the first post that erased the link. I re-posted it so now it works.
That 3d chess sounds...interesting.

LOL you couldn't pay me enough to play that one. Chess itself is too complicated for me at times, much less 400 pieces hahahaha. :)

That's nothing, you should check out Dai Shogi. It's based on Shogi (the Japanese cousin of chess), on a 15 x 15 board, each player has 65 pieces of 29 different kinds, almost all of which can promote, and another 9 types of pieces that only show up as promoted pieces.

"And if so, could it be added to this site along with standard chess and the new chess960? Maybe even Shogi or other forms of chess could be added to the site."
Shogi and Xiangqi, maybe, but certainly not any random unrecognized chess variant. Chessvariants.com has its own GameCourier for playing online correnpondence chess variants (http://play.chessvariants.org/pbm/index.html), although the interface is awful.

Wow, that will be incredibly hard to keep track of! (it gave me a headache by looking at it : D)

My impression is that this game would simplify down to a more manageable number of pieces very quickly and then wouldn't be t hat different from regular chess except y ou'd have a lot of extra room and various weird pieces. So, what's the point of having so many pieces starting out?

the board have to be really small for peoples to reach to the other side of it, it can be very frustrating with those small pieces
Well, this game must be called 'Giant Chess' because of the 'Giant' pieces occupying 4 squares. Not because of the size of the board. Taikyoku Shogi is played on a 36x36 board with 402 pieces per side.
A very interesting game that is also played on 16x16 is Tenjiku Shogi ( http://hgm.nubati.net/tenjiku/tenjiku.html ). It features Fire Demon pieces, which 'burn' (capture) not only the piece on the square it lands on, but all neighboring opponents as well (somewhat similar to Atomic Chess).
I was wondering if this game of chess really exists: http://www.chessvariants.com/large.dir/giantchess.html
And if so, could it be added to this site along with standard chess and the new chess960? Maybe even Shogi or other forms of chess could be added to the site. This is Chess.com, not Standardchess.com
