I finally decided to get Viscera Cleanup Detail. It's been on my radar for...I guess years now. I got Santa's Revenge a while back, and I decided to give it another spin the other day but it's too early. So despite never having even completed that little stand alone in at least 2 years of having owned it, I got the whole game instead, and it's pretty fun.
Or maybe that's the wrong way to put it. It's relaxing in the same way as any game with repetitive play can be, and finishing a level is immensely satisfying. So it's not fun in an excited to play way, and I find it can be rather overwhelming as you start out in a given level, but damn, when you drop 3+ hours getting a level clean, fixing the damage, and getting things organised...it feels good.
Plus I love doing the whole CSI thing at the start of the level (where you basically work out how everyone got killed for bonus points).
Also, I'm not sure if it was intentional or not, but playing the game I feel like I'm less a cleaner in the janitorial sense and more in the criminal sense. That is, I'm pretty sure my services are being engaged to cover up these 'incidents' entirely. At least, I like to think that. Helps me take pride in doing a good job.
