This plugin does not and has not to take care of the type of game is the target, it's not the task of the producer. The producer makes an "all purpose" plugin that generates planets as detailed as possible. It's up to the game producers to use it the right way. In example, you could use the planets in a Elite style game only as "fillers", where in reality the only parts of the planet used are spaceports. Or you could make a huge MMORPG where are the same players to build up stuff on the planets. Planets in the demo are very small compared to Earth. I don't know if it's possible to make larger ones because as Imerso said, I'm not a customer yet but I suppose yes. About comparison with a real picture, you can't see anything with a cloudy sky and everything looks flat. Apart this, you usually don't want a flat surface in a game, it looks boring as hell and quite useless (not very fun to fly over it), so, often in games there are many more mountains than in reality. Keep in mind you can meet a huge quantity of variation in landscapes even only in our Solar System.
