One thing about innovation that's never felt quite 'right' is the scoring system. To qualify for an achievement you need age * 5 in score. But not only do card points get more valuable as you go up in age, you already have score from previous ages to buffer your score. To qualify for the NEXT achievement you just need 5 points, which gets easier and easier. This makes the score system start to feel really broken somewhere around ages 5-7.
I know the ages are supposed to be get faster paced over time, but the way you score cards becomes more powerful as well as the card values. There's no need to make the score thresholds even smaller compared to card value on top of that.
I wonder if the pacing would feel better if you needed two cards "per age" to score. That is, 2 points for age 1, 2+4 for age 2, 2+4+6 for age three and so on. So it would be like:
Age Vanilla New
1 5 2
2 10 6
3 15 12
4 20 20
5 25 30
6 30 42
7 35 56
8 40 72
9 45 90
Do you think the vanilla system's crazy scaling was intentional, or just that it's easier to play by multiplying by 5 in your head rather than looking at some chart?
