In Eco Lifestyle i'ld have made the trash spawn along with the industrial print in any neighbourhood of any world (with a cheat code to make neighbourhoods super dirty with just one click :lol: )
In Discover University i'ld have made university last two weeks max, with 2/3 credits each.
In City Living i'ld have made posible to build apartments, or at least, have a category for apartments in the gallery.
The only gripe i have with Get Together are the premade clubs that are hard to delete and are spawned constantly to keep a minimum of 11. I'ld have added a button to easily delete them and would take away the minimum amount of clubs. Sometimes i just don't want any club in my game or i want only my clubs, the clubs i created... but the game keeps respawning premade clubs...
In Get to Work i'ld have made posible to run a retail store from home. I bought the pack mostly because of the retails but this is the reason i almost don't play them... (although i ended up loving the active careers and the aliens too :) ).
I find this thread very interesting. Now that devs are going back to upgrade older systems it's really nice to know what are the things people would have made different.
Now i don't have enough time but later i will be back to talk about game packs.
