For me, there are three big problems with the worlds they create:
1) Lots and world objects can't be edited. In TS3, you could add/remove lots and world decor, which meant you could customize the world. In TS4, there are lots I don't use because there's world decor that I can't alter. In addition, there are plenty of lots that aren't a great size or bizarrely don't meet the road or fill a space as completely as they could.
Examples include houses in Strangerville/Glimmerbrook with stone planters out front that I can't remove, or the house in downtown Copperdale that is half the size of the neighboring shell house yet has loads of empty room behind it that is unusable, or that house in Tartosa on the top of the hill with a strip of empty un-editable land around it.
2) Neighborhoods are getting bigger and bigger, but the worlds feel empty and fake. Compare the feeling of the neighborhoods in Willow Creek, where all five lots are together and you can create neighbors, with the feeling of later neighborhoods like Evergreen or Copperdale where your sim is surrounded by empty fake houses. Also, bigger neighborhoods feel empty and lifeless when there are still only 20 active sims loaded at a time. Copperdale feels like a ghost town in my game.
3) There aren't enough lots. Since we can't add our own, all players are being capped by the needs of players who have the least powerful gaming set-ups. I'm not asking the team to cut off those players, but if they gave us the tools to edit worlds ourselves the control would be in our hands. San Sequoia only has 12 lots - perfect, perhaps, for a player whose PC can't handle any more than that. But mine can, so give me the tools necessary to add another 10 lots in my game.
I'm not sure if I would buy world packs, because I have a problem with the team's apparent design goals for the worlds they produce. World tools that let you edit the world, so we can change and customize things the way we want, would be the best solution in my opinion.
