I like buying bundle deals of games, or whenever a game becomes super cheap I tend to try and get it. Today, The Humble Bundle had a new special from a company that I never heard of before today, even though I'm pretty sure they are the company that was behind System Shock 2. But on that bundle had 2 FMV games, 7th Guest and The 11th hour. Both games I tried playing and I had a smile on my face the whole time.
So my question, what is you're best or favorite random purchase that you made?
