At the end of last night's playtest, someone (@Brainiac4?) pointed out that there was very little reason to set a low speed. High speed gets you to checkpoints faster and makes you harder to hit. Low speeds let you shoot first, but there's relatively low value in that.
So, in part, this is by design: Slow turbines aren't very interesting. But on the other hand, plenty of things have veered away from my original design intention because it turns out that they're more interesting, or more fun, to more players, than the original idea. So I want to explore this idea.
One suggestion that was made was that slower turbines ought to get a larger hand size. Although that's procedurally difficult under the current rules (because you draw in the end phase, then set your speed at the beginning of the next turn, after your hand is already full), it would be relatively easy to say something like,"Turbines with speeds of 1, 2, or 3 get to draw 3, 2, or 1 extra cards, respectively, after speeds are revealed and initiative determined."
How does that rule grab you?
Would it convince you to set slower speeds in play, do you think?
