How is it linear? Not trying to challenge your statement, I'm just genuinely curious. What's the main line(s)?
There's a lack of moves. There are only 5 moves to start the game. (if pawns can move 2 squares, then 8) And the only viable stratagey is to push pawns one square at a time.
(Note: I am not a CGA but even i can see that there's a clear problem with this variant, which is lack of moves and stratagies)
