in the old game, if you load it after the new one, you will be able to see a lot of familiar things, but there are more differences than common features. In the new version, the plots of the quests have been changed, new characters and locations have been added, the roles of some old characters have changed. At the same time, some of the features that were in the old version have been removed in the new game, some enemies and items have disappeared.
In general, I can note the following features of the old game: 1. Poor graphics. 2. A more dangerous and difficult beginning of the game for the protagonist. 3. Not a very convenient interface.
