I’m actually very impressed with how much of the Sims 3 EA managed to squeeze into this little DS cartridge. Seriously. Your Sim won’t die, or have kids (or ‘woo-hoo’), and the max household size is two, but other than that, the game is pretty much intact.
You can still build a Sim from scratch. Still create the most awesome, ultimate house imagineable. Still become a mad scientist. Still run around like an idiot until you’ve caught enough fish to fill a super market. Talk to everyone in town. And so on and so on. None of it is quite as in-depth as the PC version, but — again — for what they’ve managed to fit into the DS, it’s damn impressive.
