Keeping track of more than a dozen soldiers with 10 skills, their inventories (including ammo count and weight), dynamic visibility, line of sight, destructible terrain, consequences of missed shots (like friendly fire or destroyed loot), etc. quickly overwhelms noobies, putting the real strategy masters in the limelight. And this is just a battle out of many, with base building, personell management, logistics, reconnaissance, research and manufacturing between them.

The openxcom team have re-implemented the entire game and fixed many of the longstanding bugs in the original. It allows you to play on modern machines and in much higher resolution. A copy of the original game is still required for the assets.
