It's Civ IV, of course this game is good. It's one of those games that is used to compare other games because this game is the pinnacle of turn based strategy. When people think of a better game then this one they will think about another Civ game. IV is the best in the series imo just because it has better AI then the new releases. Great job GOG for adding this game into your library. The expansions are in the game folder. If you try to start it from the GOG menu it will start Civ IV classic.
