I am afraid that I have to agree with George Duke's well articulated POOR comment. RN and BN too powerful on an 8x8 board with only 8 pawns to 10 pieces. Disagree with George only in that I believe Omega plays excellent compared to this shoddy little variant getting a bit too much publicity. Here s an improvement using the drop concept in this game: use Joyce's short range war machine/knight and elephant/knight compounds instead for a more balanced game.
So Excellent for the whole drop concept (though I would prefer that the player pay the price of 1 move to bring in a piece), and Poor in piece selection.
I understand the enthusiasm of previous commentators of bringing in new pieces via gating but why use a knight compound anyway: Just drop a real Elephant (modern type) and war machine/wazir and maybe 2 ninja pawns - thats a bit more subtlety than just going crazy with powerful knight compounds.
