Okay, impressions for about 3 years in Friends of Mineral Town!
Holy crap this stuff is addictive!
It was really sad, the way I was pulled into "just a bit more, bigger rucksack" to "just a bit more, better house" to "just a bit more, better tools" to "just a bit more, marriage."
But, now I'm married, with a son, and pretty much have nothing left to strive for but the Mythic Tools and the 100 mil villiage cottage, and I feel like the game is pretty much out of steam. Incentives really aren't that exciting. I think Alex once criticized Animal Crossing (which I am now strangely, sadly, more interested in), but given that the ultimate goal in Harvest Moon is essentially to have a lot of money and pretty houses, I don't see too much of a difference.
I just think the game needs something more. It would be really good as a sorta "make your own villiage" minigame that most RPGS have where growth here lead to something more tangible in the main game, regarding combat. Which isn't to say that it's not a good game as is, but it is a little unsatisfying in the long run.
Oh yeah, and I was reaqlly surprised to see comments that Harvest Moon GC was too radical or whatever. I read about the changes and it seems like the kind of minor, incremental step I would be disapointed not to see in a sequel.
In conclusion, I might be interested in another Harvest Moon game somewhere ten years down the road. Or maybe I'd just rather own my own real farm......
