This came up recently in another thread, about how Shadowrun was cool, but the Dragonfall expansion made it awesome.
Anyway, 2 pieces of news in case you were not aware. Dragonfall was re-released as a full stand-alone game called Shadowrun: Dragonfall - Director's Cut. If you already owned the original Dragonfall, it's in your Steam library for free. There's apparently more stuff in there and some improvements, yada yada. From the Steam page:
The second item is that there's a new expansion or whatever, Shadowrun: Hong Kong. It's in pre-purchase right now and discounted to $19.99 at the moment. Regular price is $29.99. Anyway, thought I'd mention it. I won't be buying it yet... too many games on my to-play list. However, some of you others may be tempted.
