In truth, I haven’t been following the development of this game at all, but the screenshots from Sims 2 look like a remarkable improvement over the last game. Not that there was anything wrong with the first game’s graphics–The Sims didn’t require fully-rendered arm hair. However, these look much better. For one, it looks like you can zoom in and out. The perspective no longer looks isometric, so it’s much more flexible. Also, some of those screenshots are pretty kinky:

Judging by these video clips, the sequel seems to have retained all of the humour and whimsy of the original.
It looks vaguely pornographic. I can’t wait.
