I enjoyed Obduction but it's the type of game you have to pay close attention to and take
notes throughout - at least I did.
Once you obtain the map of the world you're in it starts to fit together. I have to admit I buy games
like this - similar to Myst - because I enjoy puzzle type games without bloodshed and am finding more
independent games to buy.
This is a trailer
for the game just in case you haven't seen it yet.
