ChessTempo.com has 5 games with 10.g4 and no other white 10th moves.
White's following rook lift idea may be unique (or I need a bigger database).

I noticed that Stockfish picked up an easy win during the reverse game (round 54.3) against Komodo 2576.00,  It already had an eval over +2.00 after only 14 moves.

After 24...Nh4? it went downhill fast!

Yes, that was an interesting game also.

Then 13. Ncxb5 axb5 14. Nxb5 Qc6 15. Nxd6+ similar, but better for white, to my home game.
