Turn-based games have been around for some time. From original XCom to Heroes of Might and magic. One day, guys at Sir-tech took that forumula, built upon their original title and perfected it to a level no game on planet has ever reached. That's Jagged Alliance 2. A game that hundreds of developers have tried to follow, but have miserably failed to get even remotely close. Even 9 years later, JA2 is the absolutely top1 TBS that everyone should play. The amount of complexity, the mood, the mature vibe, the play on 80's brawler movies, memorable characters, so-called "gun porn", delightful isometric art and fantastic gameplay is something any strategy game lover has to experience in this lifetime. I have little doubt anything so well done exists or would exist in any foreseeable future. JA2 is perfect at what it does and how it's implemented. Once you go through Vanilla, install 1.13 community patch or any of the numerous mods and add hundreds of more layers to it.
