Since I played the flash version of The Binding of Isaac, it quickly became one of my favorite games of all times due to its amount of content, the unpredictable runs, its difficulty and the huge effort you have to put to unlock all the content. With The Binding of Isaac Afterbirth everything was improved including the look of the game, its stability and performance, the content, unlockables, bossed, mechanics, etc. making it the best version and a must play for every gamer who wants a challenge. Unfortunately, unlike the steam version there too much to improve in this GOG version, my biggest complaint is related to achievements, which are not available in this version, also the mod support is something that many steam players who might want to get a DRM-free of this game version will miss. I will consider to modify this review if in following updates this gets fixed.
