Well - as you probably know from other reviews, Viscera Cleanup Detail: Shadow Warrior is a free gift for users who purchase Shadow Warrior, so in this case we can't talk about price-value ratio.
This leaves us with enjoyment-time ratio - it was free, but does it worth the time to play?
The game is really simple: clean up the temple. You have your trustworthy mop (press 1) your hands, trained on numerous temples you cleaned before (press 2) and "The Sniffer" (press 3) which can detect blood and clutter around you (left click to turn on/off, right click to change mode)
The game mechanically both simple and great. You need to clean the place up - get shurikens, katanas, guns and smashed statues to the incinerator, as well as mop up the blood and clean up the severed torsos, limbs, internal organs (Hey, they had a wild party previously!) The little trick is in the later items - bumping into objects, kicking body parts will splatter blood around, and if you step into a blood puddle, you'll leave nice bloodie footprints for a while.
You don't need to take every single item to the incinerator - there are yellow crates in which you can dump items, then bring them in one turn. Basically this is the most intresting part of the game. It's because the game is kinda more physics-simulator than a real game. You can actually throw/put items into the crates, and you can shake them out of it. Tip it over. Collide with a wall and drop it.
The game's physics great, and actually somehow the theme also fares really well. I was mainly playing this when I was too sleepy to play with anything that requires thinking, and actually this was quite a good game for that purpose - I finished it in about 3 hours.
Sadly I can't tell anything from the multiplayer options, I haven't tried it out yet.
I don't know if there is any point of writing this review as currently the game isn't sold separately but at this point I think I summed the game up quite nicely, maybe some of you will find it useful eventually :)
I liked the game, it's really like a good old household chores - while you do the cleaning and menial work, you don't really need to pay attention, you can think about everything you want. It was a great experience from a free gift game.
