I think its a great site, especially since it uses, what looks to be, monopoly houses! :-D But for some well designed sites, I have to put forward.... www.ffonline.com www.r-fate.com (self pimp but i love it!) www.worldofwarcraft.com (Amazingly well designed) www.lineage2.com Ill try to think of more for you!
the best one ive seen recently is ownyourc.com other than that, it will take days to list all my favourites
Midi files, tacky flash, ill done edges on the graphics... but you know what? That actually all comes together really well for a really nice homely feel!
