KillTheG1mp: Yeah but the matter is not installing, is the "downloading"... ;)
700mb is not 2gb...
When you have not intentions of playing (at least for now) commandos 3, it's like downloading 2gb of junk that will stay on my HDD and impair my 30gb monthly download limit that my ISP imposes me as part of my internet package.
GOG.com sells Commandos 2+3. GOG doesn't sell these games separately. If you want only one of them then you can get them elsewhere, such as at retail (I think Sold-Out still do Commandos 2, and Steam sells Commandos 3).
Oh, 30GB limit? That's 1GB a day, so downloading 2GB is only 2 days worth of usage. I'm sure can spare two days. My limit is only 10GB.
