Game 1: X-Wing Alliance. It's actually one of the top 10 games I've played in my life, but when I bought my computer wouldn't run it! Took me 3 years before I upgraded my computer to finally play it, and by then it was dirty cheap lol;
Game 2: Now, for the real turd, I'm gonna go with ... tadada-da, Superman 64. Yes, I bought it at R$ 200,00 Reals at the time, wich would be roughly US$ 120,00 dollars at the time. Oh, if only I knew what I was getting myself into...
