Now that I know I can run it, I may bite.
Holy shit, I just finished the first Dark Forces and it's one of the best FPS games I have ever played.
Like, I would seriously put it up there with DOOM 1 & 2 / Duke Nukem 3D. Underrated as fuck yo. If you like old school shooters and / or Star Wars, I can't recommend it enough.
Now to begin the Jedi Knight trilogy. Weeeeee.
Sam and Max Collection
Monkey Island 1, 2 and Tales of Monkey Island - The first two Monkey Islands are essential, some of the best games of all time. If you like them, you might as well play the Telltale ones(Tales of). Of course, you should make an attempt to find a copy of the third Monkey Island, The Curse of Monkey Island, even though it's not on Steam. It's my personal favorite... The fourth one, Escape From Monkey Island, is not really worth going out of your way for unless you become a HUGE fan. Whatever you do, don't get the PS2 version of EFMI.
