I have finally done it. After playing this game for 5 years and God knows how many hours, I have reached 1 million stubs!
And I didn’t pay a cent!
EDIT: I've now reached the 2,000,000 mark! Without paying a cent!
EDIT 2: 3,000,000 now! And aced my exams. Feeling good!
EDIT 3: Just passed the 4,000,000 mark!
