My first one was Friends of Mineral Town on the GBA, which is still one of the best IMO.
Right now I'm still going through Harvest Moon DS (I skipped it and went straight to Island of Happiness) and am loving it. (Though it is stupidly easy to get money since there is an easy gambling system)
I've also had a few romps with the console games, but Harvest Moon is always the best on a handheld.
After trying to convince my CoDbot friend that its not just farmville, hes been playing it regularly now.
His words were "Its a stupid premise with stupidly repetitive gameplay, but I can't put it down."
Anyone else like the games?
