The original was a great game, and I remember playing it a lot in my earlier Gamecube years. Later, it took me two years to convince myself to buy WW, which threw me off due to the hole curving town thing (being accustomed to flat acres). I got bored with it after a while, and locked it up in my closet, until I suddently heard how one could make roads and terrain and such, renewing my interest, and causing me to yank it out of the closet (so much for my plans on growing that Rowrap Tree... in Diamond) and get interested playing with it again! Course, time travel abuse helps, too. ;]
Note: Do NOT go 20 years in the future and then 20 years back just to see what will happen! You'll regret it!
