I have high hopes for the 3DS version. I played the DS Sims 3 and it's pretty much an actual Sims game, none of that minigame crap that happened after Bustin' Out.
The DS game feels like it had a bunch of stuff watered down and literally mashed into a lower format, almost as if it's a hand-me-down version of the 3DS. It feels like an unreleased version of a final game, sorta awkward, but completely playable, and if you give it a chance, you'll have fun.
It's about time Sims went back to being cool on the consoles. It's first shot and it was awesome, second, like an expansion. Then it shot itself five times repeatedly and died.
But hey, it's back now!
