I saw the thread games that disappointed you thread and figured it would be fitting to make a counter-thread. What games have you purchased with little to no thought and ended up having the time of your life? You could also answer what games do you feel lived up to the hype you felt when you got to play them?
Personally one game I bought and didn’t think of much was Dungeons of Dredmor. I saw my cousin playing it on steam and figured I’d check it out. I bought it for I think 10 bucks and it was the time of my life. It was harsh but fair, one of the most rewarding gameplay experiences. I went in thinking its a mindless hack and slash to find one of the toughest turn-based strategies I have encountered.
One game which I think lived up to the hype on launch was FTL. I was really excited about the concept and I think the execution was spot on. Good music, challenging gameplay, and a price tag you can’t beat.
