Oops, I mean 'KOTOR'
Knights of the Old Republic (KOTOR) is one of the most memorable games I've ever played. I can still recall the day that I picked up nonchalantly because I was a fan of Bioware's old works and Star Wars collectively, but nothing could have prepared me for how good it really was.
Many years later, the game was ported to the iOS platform, and now you can pick it up for half off the current price, at $4.99. No real reason or announcement was given for the drop, so it's unknown whether or not it's temporary or permanent.
