I also played The Sims/The Sims 2 on my PS2, and the controls were pretty accurate, you just moved around the cursor with the analog stick. It normally moved awfully slow, but you could speed it up (if I remember correctly, it's been a lot of time) to be quicker. Scrolling through menus did take a lot longer, though. The difference was astounding when I later tried the game on a PC (especially content-wise, so much of it didn't make the cut in the PS2 version, most likely to make it fit in a single disk).
