It would be great if I could have,
Stuff Pack
1. Hobbies - introducing more skills, activities, sports
2. Martial Art or anything related to self defence. Superhero theme
3. Rock band related - giving us a proper trailer that can be lived in & a venue for performing with new event such as music festival
4. Home business - SOHO theme
Game Pack
1. Vacation with Alps/Alpine, Far East, or even savanna theme - Having a ninja would be awesome & it will be great if one of the BB is a horizontal door. I want to make a trap house! Hiking & introduction of wild animals, or llama.
2. Supernatural, something new & Simmish. Like how they introduce the PlantSim. It would be awesome if there is another occult state created by the Sims team. The werewolf, fairy, gargoyle, zombie etc are fine, but I wish that there is something new & different.
3. Historical with medieval theme where its allow the Sims to experience living in that particular era
4. Theme park world where it can be one of the destination that the Sims can visit & play.
Expansion Pack
1. Time travel with steampunk theme. A lot of machine, air ballon, airship, etc.
2. Simlantis - were it focus on living under the water - either living in a submarine or the underwater capsule for example
3. The underworld - it's a world after life. I wish that they could make another world full with ghosts, spirits, angels, skeletons, etc. It would be interesting if we can continue playing with the ghost (not in the current Sims world) in a world where they could live, work, and play.
4. Outer Space - with the hope that they could make the Alien more interesting & perhaps giving us the Sixam to be a bigger world itself. With the hope that any other Sims can only travel there either via a rocket or the wormhole.
I do believe that there's a lot more that the Sims team could create & develop. I just hope that it should be something unique, unpredictable & most importantly, replayable.
p/s: I don't put any farming related because I know it's going to be the next EP (finger cross!)
