Very legit concern. Although I've tinkered with a few things, I haven't played a new (or old, for that matter) game in almost 2 years now. My shelf is a shameful dustpile of great titles—Gothic1, Drakensang1, X3, Witcher1, DivDiv, another Wiz8 run, Eschalon2, King's Bounty: AP, purchasing and playing Frayed Knights…
I'm a monogamous gamer by nature, which just makes it worse.
OTOH, I'm having a great time, which is supposedly the point of our hobby in the first place.
