What is a game series you never touched or actually played (but owned)?

How can you buy a game and not play it? That's absurd.

I could understand if it's a gift but otherwise;...

Because games are cheap and maybe you buy them to play later? And then buy another game to play later... and on and on.

Some people actually collect games and some people buy games to sell them later for profit.
