Mine was SimCity 4. Ever since I was very young, I loved the SimCity games. I was addicted to the original, then 2000, and later SimCity 3000. When SimCity 4 came out, and I finally got a computer that could run it, I rushed out to buy it. SimCity 4, although the graphics were unbelievable compared to the previous games in the series, didn't have that same addicting feel as the previous games did. For example, it was much more time consuming just to get a city started, plus, the whole "region" aspect of the game I didn't like. I did like the graphics, though. But anyway, that was probably the game I was most anticipating but was let-down by.
