+ ...(Almost) Only the initial position changes, but this is a very big change.
+ In particular, castling would be rather pointless so it's disabled here.
+ En-passant captures are impossible because all pawns already reached 7th rank.
+
+h3 Note on initial position
+
+p.
+ Since truly random start can allow un-defendable mate in 3 with a knight,
+ the kings touch at least one knight in the initial position.
+ This allows to move free out of potential check from the very beginning.
+ Here is an example:

+ | fen:r7/2n5/1q6/5k2/8/8/K7/8:

+ The king cannot take on a8 because it's guarded by the knight: it's checkmate
