Earth 2140 will be one of my favourite games forever. BUT as the others commented, AI is crippled and I wonder how is it possible that GOG sell game that is not working at all. Since the multiplayer is crippled as well and you can play only campaigns, it is a true waste of your money... To clean everything on the map when opponent is not producing anything, it is not a fun at all... Otherwise I would give 5 stars
