Well, judging by Steamspy, and by the posts in this forum I bet you it is more than ‘Some’. But It’s great it is enough for you. I still feel mixed emotions reading completely black and white posts, people 100% hating the game and people 100% loving it. Anyways, it is good you are feeling extremely satisfied. This game has been built with VFR, low flying in mind. As quickly as you ask it a bit more, it breaks.
That said, there is a little addon for the game, that lets you see the LittleNavMap using the in-game map. I don’t know if it is still working, but it might be worth the try.
