I'd say rating to 10 for each mod
it would be most fair
another idea would be to offer options of voting with .5
like
1
2
3
4
5
5.5
6
6.5
7
7.5
8
8.5
9
9.5
10
would make ppl think better before hitting 10/10 out of laziness to assess correctly the mod's value.
thanks for making this topic and poll for choosing the rating system
you rule!
