Quite honestly, I'm surprised so many people enthused over at Sandy's intro about this game. I love it, such a mellow, fun game to kill thirty hours with.
For those not in the know, it's farmvil, but good, combined with Japanese eroge. The goal is to take a rundown farm and repair and improve it by planting vegetables and fruit and raising animals. Time and stamina must be micromanaged as well as monies you get from selling farm produce and wild vegetables. You can mine the earth for valuable ores for cash, or to upgrade your stuff in certain games. Fishing, foraging, splitting wood to upgrade your house, all walk the line between super fun and borderline mine-numbing.
If you haven't, emulate that bitch. Start out with an older version, Friends of Mineral Town and 64 were both solid. Magic Melody and Wonderful Life are more whimsical. Newer ones for the DS and WII have kinda gotten away from the dynamic that made the older games so great, but are still worth a play.
My favorite is Friends of Mineral Town, although I have fond memories of 64 and the original Gameboy, which were the first two I played. I've put some solid playtime in all of them, except for Save the Homeland on PS2 and one of the newer DS games. (That I just downloaded and will play when I get some free time)
Karen was my favorite back in the day, I have a soft spot for the tsundere types. Plus, if you didn't befriend her, she'd run away from her abusive father. I definitely have a soft spot for the 'protect me' type.
I wish I could have put more time into Magical Melody. The customization seemed cool, and there were lotsa love interests.
