Some of you might remember that I'm the Lead Journalist for iFanzine.com, and here's my personal Top-Ten list for 2015. I personally certify that every game on this list is fully worth your time, and half of them are even available for free. So - assuming you have an iOS-based device - it's my personal opinion the above article is fully worth reading (but I might be biased, seeing as how I wrote it).
(By the way, CTU-25 is still coming. However, we've since made the decision to split the script into two separate episodes. Normally I wouldn't mention something like this, but it has pushed the promised "Thriller" sequence back another episode.)
