SS1 and SS2 are entirely disconnected story wise, aren't they?
I've played a little bit of the game yesterday and realized I am going to need to work out something different from controls. The whole touch pad mouse isn't cooperating very well with this one. Maybe it is just because I haven't played a first person game on my computer for a few years now, since I bought the 360, and am out of practice. Hard to believe I did a Half-Life-a-thon on this thing, beating Half-Life, Half-Life: Opposing Force, Half-Life:Blue Shift, Half-Life 2, Half-Life 2: Episode One, and Portal with just the keyboard and touchpad mouse (Half-Life 2: Episode Two ran way too slow which was one of the major things that prompted me to run out and buy a 360 about a week after this several month long marathon was halted on the cliff hanger at the end of HL2: Episode One).
Maybe I just need to whip out an external USB mouse to use in the meantime. I guess I can deal with that through the duration of the game.
Between System Shock 2, Grim Fandango, and The Neverhood working flawlessly, I've been having some really good luck with unofficial ports lately.
