What game was the biggest waste of your money?

For me it would have to be FFXIV. I never played FFXI, and I still had fond memories of past standalone FF games like ff4/6/7/8/9 so I thought:

Hey, I should go all out and buy the collectors edition !!!!!!!!!

...

It was like I took a hundred dollar bill, and lit it on fire. Actually, no, at least if I did that I would only have been out of a bit of cash. Playing that game actually caused suffering on such a scale that I am still trying to beat back the feeling of nihilism the experience spawned in me. I remember clearly the sense of total disbelief that ANYONE could craft a game so terrible and release it to the public.
