But grandpa, how did you earn a sense of pride and accomplishment if you didn’t throw real money to the business men for every little thing you do?!

Back in my day we unlocked characters by pressing a series of buttons in a specific order and at the right moment

It felt rewarding.

Was just playing Sonic Triple Trouble 16bit and unlocked Knuckles at the end, which not only allows you to play with him but the levels/story line is unique. Pleasant surprise!
