I pretty much never finish any games. I always get about 90% of the way through, then get bored and start something else. Case in point, I'm about 60% of the way through three different Spyro games, and find myself playing replaying FInal Fantasy IX instead.
Oh, and I've found a new favorite online TCG; it's like a cross between Hearthstone and Fire Emblem. :D So I've spent most of today playing it...
