So I know a lot has gone into making games look as realistic as possible but I think very few games have put a lot of work into having a giant game.  I think the best example of this has been Crackdown (which I have recently started playing again).  I find it really nice to be able to have one load screen the first time I start playing and then be able to move anywhere in the huge game world without another load screen unless I die.  I have to compare this to Oblivion when I was playing that because every time I had to enter a dungeon or city there was a long load delay.  Given Oblivion looked WAY better and had lot items that could be picked up/stolen at any point.  But I have to say that I have had a lot of fun the last couple days just wandering around in Crackdown just shooting at things.  Both of these games have been my favorites of the last couple years because there was so much to explore.  I remember having a lot of fun with Grand Theft Auto too and I’m really looking forward to GTA IV.  I wish more games had this much to explore but I can see how it would be a lot for developers to do.
