Invisible War feels like a title that could have been and perhaps should have been better. In addition to the issues already noted, there are smaller, niggling ones like mouselag in the default.ini file, which makes your cursor slide to the general vicinity instead of moving precisely - not all that difficult for most gamers to fix, but we shouldn't have to. As well, even doing every side quest I could find, I completed the game using a combative approach in a rather short time, less than 12 hours including re-loads. A second character, sticking closer to the central storyline, took only about seven, although reports indicate methodical players can expect around 20.
