The story might start slow, but actually imho it turns into one of the best in computergames. I really loved that game and it was one of the few games, where even in the end, i still talked to absolutely everyone and tried everything and completed every subquest and not like in other games, where latest at the half of the game i turn into speedmode and just rush through. You get a few choices in the storyline, but neither is black-white (usually all options are dark grey in hindsight ^^) I actually played it again after first playthrough and it still got me.
In the final version also most annoying things are fixed, so bugs are gone and loadingtimes are not such a huge issue anymore. (It worked very slowly on my old laptop in original version, final version ran okay, and my new half year old 500 euro laptop has absolutely no problems with it at all)
So if it is cheap, i would for sure recommend it.
