Maybe not the best option at the moment, but the GTX 1660 TI was a really good value for a long while. About the same power as a 1070. Could probably get one cheap used.
I found a copy of the game online because I wanted to try it out before I considered buying it (I had a feeling I wouldn’t like it). I got maybe an hour of playtime before I stopped playing. The new pretty skin doesn’t do enough to make the game worth it.
Time to take up sailing?
