Is that you don't want to stop playing them!
Unfortunately you just don't get the time you need to play completely through some games. Obviously I want to get a review done every 2 days and now I'm reviewing larger games too time just disappears!
However, I have managed to find time to give "The Spirit Engine 2" a really good go. So a review will be posted later tonight based on how far I have progressed.
Otherwise there are other reviews waiting to be finished off - expect another "free game" review on Thursday!
