Very nice result. I do like the bishop.
I have to say, I also don't generally like "specialty" type sets, because if you have to think too hard about which is which, it confuses the game, but these I think are very much in keeping with traditional sets. I'd have play a few games with them to be sure, but they certainly seem to be very "accessible" as it were.
About the 4 player chess set, are you talking about Sceptre?
I friggin' loved that game. Used to play it all the time when I worked in a comicbook/gaming shop in the mall (that was years ago).
It was chess, played on 9 terrain'ed boards that could be rearranged arbitrarily for each game. It stuck very close to the standard chess rules, except that terrain had an effect on the pieces. Definitely not classic chess, but a lot of fun.
