Kirby Superstar... It's kind of ridiculous...
Bought it for the SNES. Lost my copy. Bought it again.
When my little brother got old enough to play games, I bought a copy on ebay.
I bought Superstar Ultra for me, and my brother. My brother lost his copy, so I bought him another one. Someone was selling a copy for a dollar... I bought it, just in case one of us lost ours.
Bought it on virtual console.
Bought it as part of Dream Collection.
Bought it on Wii U VC.
So I bought it ten times. And I regret nothing.
