Dad gaming?

I've been away all week so have missed all the news, but clearly the biggest issue today is what game to get for Father's Day? My kids are 2 years and 4 months old respectively so I'll let them off for now. But my real concern is what game to buy for my dad. I've never bought him a game before but he has just splashed out on a new PC and is looking for something to play on it. Or at least I'm looking for something for him to play on it. He hasn't really expressed any interest before but hey, gaming is mainstream now right? So any suggestions? I'm thinking maybe Civ or a point and clicker or something. Forget games for girls and mums, what do you buy for a 60 year-old man? And if you're a dad, what gaming goodies are you hoping for? And no, "time to play what I already have" doesn't count.
