This is the sort of game that you never get tired of, even after months of continual play! Truly brilliant!
Animal Crossing: Wild World puts you in a virtual world where the townspeople are animals and the main sources of income are fishing, archaeology, gardening and insect-cathching. Whilst on paper this may sound like the world's worst life simulation, it won't take long before you are absorbed into your town's little ways.
This game has such an open-ended gameplay that you really can spend about an hour on it and never do the same thing twice. Talk to friends, fish, dig fossils, catch butterflies, plant a tree, fix the garden, re-decorate the gouse, design the latest fashion, shop, watch TV...practically anything!
Throw in a whole bunch of wacky but loveable residents (KK Slider, the greatest canine guitarist ever; the Able sisters, who run the tailors; Resetti, the short-tempered mole who screams at you when you switch off without saving) and you've got the best DS game there is.
The crowning glory, however, is the amount of hidden features that are in this game. Yes, three minutes searching on the internet will give them all away, but if left to your own devices, you'll be discovering new things about your town for months on end.
Are there any flaws to this game? Well...a few small ones. The tocuh screen controls could have done with a bit more work, but the button alternative works fine (so long as you don't use B to sprint - use L or R!). Occasionally you wander to yourself why certain features can't be included, such as more hat shapes or hairstyles, but these are small quibbles compared to the amount of positive points.
Unforetunately, I have no Wi-Fi access as yet, so I am unable to comment on the games online content, but just playing by yourself (and contact with the other three humans you can create) is enough for me!
