How about a PGN file with a comment after each move? I'm not sure of the
precise pgn syntax, but are't comments/annotations allowed if enclosed
in parenteses? That way you could store the summary info after each move
in each game to keep the file size from getting too enormous. If the
file was allowed to contain games beginning from a non-standard
position, say in FEN for example, such as might be used for chess
studies, then you could achieve a tree structure by including game
numbers as comments to moves - the idea being that the games referenced
in this way are the children of that node, and start from that position.
The file might look messy, but should still conform to the standards
required by other readers/viewers, and it would save a lot of space.
