The add-ons for the deluxe doesn't fit my taste. It would be nice add-ons if you want to do styles other than EA's "generic" theme. The UK style looks kind of cool I guess.
Only thing stopping me from pre-ordering is I keep hearing the map size is going to be tiny. Something like 4km^2
For me this is exactly the reason why I will not buy sim neighborhood 5 I mean 2x2km is the size of a neighborhood. sim city4 the largest area was 4x4km ans still feel very small, only cities xl had the perfect city size 10x10km.
