The only WiiWare games I own are Mega Man 9 and World of Goo (both excellent). I got Strong Bad for PC. There's more I want to buy but I'm low on cash at the moment and I don't have the abundance of time for gaming that I'd like.
I have lots of Virtual Console games, which is kind of reprehensible since many of them are games I already own for their actual systems. I've found that beating Double Dragon, Ninja Gaiden, or Super C in single, 20 minute binge sessions can actually be therapeutic during times of stress.
