Re: New to Starmada
I calculate ranges differently than Dan does, and have slightly different movement rules (and 3-D).
However:
I calculate the surcharge for ranges as a quadratic function (Mike Dugan, you might want to avert your eyes. Scary math ahead):
For a 3 band range bracket (say 5/10/15), the costs run like this:
5^1.732 (16.241) * %chance to hit * damage
10^1.732-5^1.732 (53.951-16.241=37.709) * %chance to hit * damage
15^1.732-10^1.732 (108.890-53.951=54.939) * %chance to hit * damage
Summing these values, we get 16.241+37.709+54.939=108.899. For a real weapon, we'd divide by the percentage of coverage given.
If we run this for a range 30 weapon with identical stats, we get:
53.951+125.267+166.261=361.721 for the range term.
Which means that double the range is roughly 3.33x the total weapon cost in effectiveness assuming all other things remain equal. (There are other factors that come into play in Squadron Strike that make that about 3.5x the effectiveness for a doubling of range).
What this is doing is abstracting for the fact that there's a volume of space that's being threatened, rather than a linear distance term.
I'd change the exponent to 1.414 for a 2-D game like Starmada, since you're threatening an area.
What this does mean is that if you have two weapons with the same "point cost", they have (to date) been of roughly equal effectiveness.
Basically, is it possible to take an equal point and speed fleet with range 15 weapons against a fleet with range 30 weapons on equal points and have it be a close game in Starmada?
