1. I don't need encouragement to buy stock any time I am able to. The returns on buying stock midgame for $4-$5 are huge, and it also drives up the price for others to buy shares.The first share bought will be worth 2x just based on the stock purchased multiplier before factoring increases in assets.
2. this seems weird and will just force everything to be priced to the same amount. Free money for the first person to build it.
3. The engineering bay is a really good building. I'm sure people will figure it out its uses eventually, like the hacker array. Remember, claims are the scarcest resource, so anything that improves the efficiency of them is a good thing.
4. It's already not easy to figure out whats going on in the limited time without fog of war. Not that fog of war can't have a role, but I can see it being a scanner building that consumes high amounts of power. Just buying scans seems like an arbitrary addition to create an interference to gathering information.
