Well, I started the game and it only had to install stuff (C++ runtime, etc.) for a minute or two, including what it said were the updates. I made it all the way to the character select screen without have to download mass patches, so I think I'm clear on that.
I'm actually relieve that my lappy will run the game. It's got an Intel 4 chipset, so I was unsure if it would actually work, but it seems to be fine.
Anyway, I joined Meneldor, but have yet to create my character. I'm going out with my dad so I won't be on until later today.
