Any Game Regret Story, Picking a Loose Cartridge Over One That's At Least Complete In Case (Has Original Case and Manual). Also Nintendo Selects vs. Regular Version?

Hi, Nintendo friends, if there are, what have you been your regrets choosing a loose game cartridge (all original) for half the price of the one with case and manual (all original), How about Nintendo Select over the regular version?

Or vice-verse, you wish you just had loose cartridges and stack them like cards- it's compact and you to buy more games?

Thank you.

God bless the Nintendo Masterace.
