So I just got a message saying I'd completed the following achievement... At first I thought "Cool, I'd forgot about these achievements". Then a few moments later I thought "Hold on...that can't be right, this is nothing really" by my calculations to get 16,840,000 Gps takes 1053 days (2.88 years!) and after committing that much time to the app you're rewarded with 4 measly skill points?! Is that really anyway to promote continued gameplay? Granted this was something I wasn't expecting so initially a pleasant surprise, but after a few minutes for it to sink in...it's really more like a kick in the pants.
And that's not even the highest achievement, I can't wait to get my 4 SPs for the next one when I get there in another 2 or 3 years!
