When we talk about the old "Combat Mission" ("CMx1") serie, we´re talking about the best 3D tactical games that ever exist on the market. They´re old, yes!, but still they´re the best, especially this "CMBB". As a tactical wargame, there´s nothing like this (yes, forget "Total War" serie: they´re games for children!). It´s impressive the amount of hours of enjoyment that such a game contains! Once you learn the rules (quite big book), and assimilate them, you see infinite tactical possibilities it has. For me, it´s one of the most fascinating, serious tactical wargame ever created. It´s like having a big table at home, a huge, realistic mockup full of miniatures. The new "Combat Mission" ("CMx2") serie (full of annoying DLCs!) are more "simulators" than "games" and, therefore, I don't enjoy them as much. Instead, the old "CMx1" are full of scenarios, different units, game modes, without the need for those Battlefront´s annoying shit "DLCs". For me, "CMx1" serie ("CMBO", "CMBB", and "CMAK") feel complete, and they´re magnificent games. The A.I. is good only in defensive positions (otherwise, it´s very bad). The good thing is that there´s possibility of playing with other people via e-Mail, or by TCP / IP connection (even there´s a "hotseat" mode!). As I said, "CMx1" is an essential, awesome game if you enjoy real tactical wargames, even today. And at this price tag, it's a bargain! Moreover, these "GOG"´s versions run smoothly on modern PCs so... What´re you waiting for??!!
