My wife is a big fan of the Zoo Tycoon games and is currently playing Zoo Tycoon 2 on the PC. I really don't know much about the games at all, but I was considering getting her a DS and Zoo Tycoon. How does the DS version compare to the PC versions?
'K. I still love the game, but there are a few more complaints this time around. Still recommend etc., you just should know what's up with it ahead of time.
AI is really stupid. Depending on how you draw your paths, a lot of the little people will keep walking back and forth on the same path. I've got a zoo with 100+ visitors, and 75+ are in a straight line. There is a neat little fix for this problem, though: save and load the game, and they'll be evenly distributed along all paths. They don't fall back into their old pattern for a long time.
Another AI issue is a lack of seeking out needs. People will be hungry/thirsty/need to pee and they'll happily walk right past a huge restaurant/bathroom. You'll get messages that warn you of "too many thirsty people," but when you see who they are, they're all right next to a shop. I've learned to ignore them, since my visitor happiness stays in the 90s regardless.
Finally, the game goes by slowly. There's no speedup option, so 12 sec=1 day, 1 min=5 days, 6 min=1 month, 1 hour=1 year. I'm to some scenarios that take over a year to complete. This isn't really a problem if you simply don't ever pause the game, though. I used to pause, build the entire zoo, and then open up for business, but then I had to wait for a long, uneventful hour to clear the scenario. Now I just build as time passes.
One thing I really love is the detail. This game would have never been possible on the GBA, as you've got 100+ little people wandering around, plus dozens of buildings, animals, plants, and miscellaneous scenery; a lot of sprites to keep track of. You can zoom way out and take stock of this grand zoo you've designed, which makes the game worth it.
With its flaws, though, I doubt any online reviewer will give it more than a 7, and probably partially because it doesn't do anything new (although the touchscreen is used admirably!). I don't know what else anyone could expect, though; it's the PC game on your DS. Like I said before, you should take a look at it if you're a sim fan.
