Fantastic story, massive replay value if you complete ever single quest. Multiple classes, good expansion. Just a solid production that stands the test.
2). Knights of the Old Republic
Similar to Baldur's Gate II in that it was an expansive and well produced story, but with fewer open endings. The narration and character driven storyline with the environments made it for me. But not Juhani.
3). Shogun: Total War
The original still calls to me, nothing beats conquering feudal Japan. Measuring your economy in rice, the varied units. It was a blast.
4). Neverwinter Nights
Another good, solid, enjoyable RPG. See a trend?
5). Dawn of War: Winter Assault
I found the story compelling and the use of the Imperial Guard for the first time fantastic. The environments alone very fabulous to play on. Xavier! Baneblade!
