The original game behaves VERY differently each time when loaded from a savegame. It concerns both tactical and strategic savegames. Just load a savegame several times into UFO: EU, and you will see what I mean. Unlike the original game, OXC seems to be repeatable, schematic.
When you save the game during chasing a UFO, and then load it several times, it will appear that the alien ship may land down in 30 seconds, 3 hours or at all. You may try the UFO: EU savegame attached to my other post, or start a new (vanilla) game, wait till the first UFO appears, then save the game immediately, and next load it several times, again and again. You will see that the scenario will be different each time.
The same about tactical game. Sometimes you finishes your move, and during the alien move one of your soldiers is being killed. In OXC he is always killed (or at least the situation can change only rarely). When you are using an autoshot, each of three shots goes to the same place! In UFO: EU each time you load the same savegame, the situation develops differently, and results of an autoshot are never the same.
Please give much more randomless to the game to make it really similar to the original one. No predictable trajectories of alien ships on the globe screen, no fully predictable alien behaviour during mission, please.
