Years ago I played Earth 2140 with only missionpack 1. And many friends from me also did. But when Windows Xp appears and I got a new soundcard I could not play it anymore on my pc, so I when I would play it I took an old pc with Windows 98 on it and with a soundcard which was compatible and so my friends did. Many times we have played this game and so I was pleased to hear that GOG was making old games compatible with newer pc's and with Windows Vista and XP. Pity that they said that it is not multiplay and that it is never implemented. I do not agree with that, because with my original old Earth 2140 and also with missionpack 1 I could play multiplay and did that many times. So I hope that GOG will implement that in future. But overall I am pleased that I could play Earth 2140 on my new XP computer, even if it is soloplay. And therefore I give 4 stars. With multiplay I had given 5 stars.
