It's not bad, but I'm with LesleyA--there are some fairly common elements of the experience of being a trans woman that were left out. For example, the game designer clearly was still talking to her family. Some of us are not so fortunate! I'm lucky that my mom does still talk to me and even considers me her daughter. My father? Not so much luck there. :(
Also, estradiol by itself generally doesn't cause breast development--that's more a function of progesterone. Estradiol does cause hair to become lighter and fainter--and this happens even with facial hair, although said hair tends to be quite coarse and dark to begin with, so one either must shave or, more usefully, undergo some sort of hair removal regimen. (I went with laser and it worked well enough that, while I still shave, what I shave isn't darkly pigmented--no more shadow! YAY!)
Ironically, in the US, the main anti-testosterone drug is also prescribed as medication for high blood pressure.
One more thing: Customs tends to seize hormones ordered outside the United States. The formulations are the same--and often the hormones are made in the same factory, just packaged and sold in different markets. But it's still dangerous because if you aren't careful you can overdose and wind up with renal failure--a fate at least one trans woman of my acquaintance has experienced.
