I downloaded it late Thursday/Friday, played it like an addict, and uninstalled it Saturday after finishing the campaign and starting a second time. My laptop did not seem to like to, though I did. I just wish the damn thing would not have crashed so often. I am probably going to install it on my PC next time I go Home and see if it works better on there (and where hard drive space is in greater supply).
... On the downside, game can be annoying for a perfectionist like me. I find myself reloading over and over so that I do not destroy any enemy mechs, just kill or eject their pilots. And that was part of the problem with crashing: when I was saving.
