lololol $200 for a dog or a cat.
Well looking at one of the earlier options, he had a choice of being able to spawn "reunited villagers". If he had done that, then I'd imagine that the villagers might feel indebted, and therefore he'd get some points back. Also, he'd have more villagers, so more feelings of indebtment. He might have actually made a new profit on points, and would have gotten more hands to work with. On the other hand, they'd burn through their food supply more quickly, which could cause tension. Then again, not sure if he could have afforded that option in the first place.
Is the world shared by the villagers of other players? because if so, I can see that getting bloody real fast.
Anyway, the dude is going to need more money for microtransactions. Dude needs to get a job at the local convenience store for now. Minimum wage in Japan seems to be 790 yen per hour, or $7 to $9 an hour. A convenience store job might be more than that, so let's say $10. If he works an 8 hour shift for 5 days a week... 45 x $10 = $45. $450 x 5 = $2,250. Subtract 25% of that for taxes and other stuff... he might be able to make at least $1,700 a week. Rough napkin math.
The real question is the nature of the fantasy world. Supposedly, it's a game simulation, but there are a few things pointing it to being a real world.
1. The tech of "the game" is impossibly advanced. He's running a hyper realistic simulation... on his old computer? No way. He'd have to be streaming that. Hope his internet plan gives him enough data. Such an advanced simulation would have been patented and publicly known to exist.
2. The sacrifices are being delivered to his house the next morning. If the equivalent fruits were grown in, say, South America, no way they could be picked, packaged, shipped, flown overseas, and delivered within 24 hours. Likewise, sourcing a log and cutting it to make it look JUST LIKE the one in the game would be ludicrous. I can see the game company maybe having some sort of property in Hokkaido that has every item in the game that can be sacrificed on it, ready to be altered and shipped to him, but that'd be insanely expensive. What if he receives more sacrifices than they have items on hand? The only other alternative to explain the sacrifices is to assume that the game company has access (or has invented) replicator technology... in which case, why hasn't this company patented their tech? This would be known to the whole wide world.
Which leads me to conclude that this isn't actually a game. It's real. The other side is actually a real fantasy world, and the interface on his computer is hooked up to the actual magics of that world. The sacrifices are sent through a portal to his world.
I wonder if they will be able to physically meet each other one day. Maybe Gams steps through a portal to the real world, or the protagonist steps through a portal to their world.
