Other fans have been fine with waiting for a new version of the game, as long as the upgrades, changes and improvements line up with the time it took to build. According to one forum, there are fans that are hoping for better artificial intelligence and one example was given.
Players would hope that guards would not attack them simply for killing a chicken in the scene, but that shows the artificial intelligence is set to attack when there is an attack. That sort of thing can turn gamers off a game and make them write wish lists like the ones we see posted online.
If Bethesda is using a new engine to create the game, developing new worlds within the game and bringing some nice improvements to the game, then the long wait will be justified. For now, gamers are going to have to wait until the Electronic Entertainment Expo to hear more.
