All good! Time limitations affected my own submission, and I definitely don't want to urge anyone to overscope. I would absolutely like to see more ACES content, though. It's a cool spin on FIST, and I'd love to see it develop further.
As for the mission in Hard West II, it's beat-for-beat identical, right down to when enemies spawn and when the train wormholes to another realm, which made me wonder if it was the inspiration. What happens after the wormhole is different between the two games, and honestly I like ACES better.
