Civilization 3 is part of a large series that many enjoy. The game is very strategic and has a computer that is very hard to beat. The challenging part of the game would have to be how strategic the game is with having to build units, set a strategic defense, create allies, trade goods, make your citizens happy as well as having to build roads and mines. Your gameing experience is based on the map and where you build your cities. The game is based around your cities and what can be taken from your suroundings as well as what can you trade for that could benefit your army and what will make your citizens happy about the wealth oyur empire has. This game is liked by a lot and not liked by many. This game is awsome, but not the best I've played before.
