I got this because of some friends wanting to group in it. NP, I got the game. It had the fun factor down. What it didnt have was challenge. I ran the Vampire, it was like I took a chainsaw to a knife fight. I bulldozed through the game with such an incredible level of ease, I think I stopped adding skill points for challenge. By the time I beat the final boss in Nightmare, or whatever the second level was called. (I accidently borked the main quest in the original. I killed one of the world dragons from chapter 4 in chapter 2 and the questline BROKE, it was the one in the volcanic area). So I restarted in Nightmare. I still wasnt adding in points, I got the the final boss and my game kept glitching. In frustration I called my buddy who asked me to get it and sent him my save game, he beat it and sent it back. I think I had like 40 points to distribute for the main big-bad and hardly got hit. I used like 4 HP pots. My friends who played it were of the same mind, fun but too easy.
Now, there were alot of details that I so thoroughly enjoyed. Read the headstone in the graveyards. "Last thing he said was, Gee I wonder if Dragons are tickelish". Or the was a huge mound "Unmarked mass grave. Rumored to be the beta characters" next one over was a defiled grave, that stone read "Developer who killed the Beta Characters".
The original was kinda buggy, but the expansion was a disaster of bugs. I gave up not overly far into the expansion due to all the quests crapping out on me. Like one early on, I had to go into some cave deal, I walk in, instead of zoning in, I am ported back about 10 feet, after i tried again, the world stopped interacting. I was told it was a normal bug. I have heard that it got alot better with time, but in spite of it being generally fun, and having alot of amusing features, the combo of oddball bugs and being painfully easy lead me away form it.
