I'd like to see Get Famous go back in for additional development, as mentioned above, but also to really flesh out Del Sol Valley a lot more, the state it is in currently is so poor it isn't worth the money of being an expansion. more neighbourhoods, more lots, places for celebrities already in the game to have their own place with their own unique flavour, it would also be nice if random sims can not move into specific lots, but other celebrities can instead, to give a sense of entitlement and exclusivity.
That silly starlight awards needs another pass over, especially around the bouncer and not allowing any sim inside that isn't a celebrity (or spouse to the celebrity) or on the job for a purpose. the area where the awards take place need to look and feel more grandiose, right now it is hardly worth being called an award show with a few chairs, and a microphone.
It is like EA have never seen an awards ceremony at all, but you'd have lots of chairs around tables, a big stage, lots of stage lights, other special effects lights, the most light is directed at the stage while the rest of the room is a little more darker lit.
I might also wish to state that the host can provide introductions and give some value between awards, but when an award is given it should be done by someone else. for example Judith Ward can come up and offer the award to Dirk Dreamer. or Dirk Dreamer and Holly Alto are on the stage to present the award to your sim. The time of how long you got to respond to get on stage and accept has to be reasonable. As it currently is there is some issue that prevents your sim for accepting their award right away. but you can accept it at another point when someone else is being awarded, it is silly in its current format.
There is so much potential with Del Sol Valley it isn't funny just how badly it has been handled.
