We'll hopefully have the front page post up today, but I strongly suggest getting started with this one immediately as it might take you a while

A quick rundown of options on where to grab it:
Physical version (1998) - available on Amazon, eBay, etc. and in several compilations.
Digital version (1998) - Good Old Games
Enhanced Edition (2012) - Windows and iPad
I am playing the Enhanced Edition on my iPad but plan to pick up the EE for PC as well and transfer saves back and forth.
I started playing this a bit last month (I am in chapter 2 currently) and must say that I feel like it has a fairly steep learning curve and starts slow - but then starts to pick up after the first few hours. Don't let the slow start bog you down!
Note: the "Dark Alliance" console games are not in any way ports of the main game, so they won't quite foot the bill for this month...
