A lot of the negative reviews here are saying that you can't use a controller with these games. This is false. You need the third party app AntimicroX in order to map the keyboard controls to a standard controller. Granted it does suck that this release doesn't have native controller support, but with this work around, you can play the games in this Kollection with any PC controller. I'm using a PC Xbox controller, and it's working without issue. Now to review the actual games in this Kollection. These games are the PC DOS versions, and not the original arcade versions. MK1 and 3 are pretty close to being arcade accurate, but MK2 is not the best port with it's subpar graphics and sound. I recommend you pick this Kollection while it's on sale, or just wait for the upcoming Legacy Kollection to drop later this year.
