How does the game play with 2? That is how I play a majority of my games and will only back it if it plays well with 2.
My intital thought is that with more players the places to put your industries will fill up more quickly so you would have to be more strategical about where to place them. There is however a dummy Corporation that you can add in that comes with the game (for solo) that will give the sense of an extra player.
Also you can play with the alternative rules that prohibits moving industries after they have been placed, either by anobydy but the owner or by everyone. This will make for a tighter more strategic game even with less players.
An idea for the designer could also be to block out parts of the territories when playing with fewer players or to have maybe 2 dummy copr. so that you can play a 3 player game solo or up to 4 when playing a 2 player game.
If you haven't tried it yet there is also a version of the game on Tabletop simulator on steam and on Tabletopia.
