I'll keep this short... cause the time it takes me to type this will take time away from playing Gothic II Gold!
This RPG is among the best I've played (over 20 years of gaming).
This new release of a 3 year old game is far better than most recent games, the story, the exploration, the character development... even the graphics, all great, all well done.
If you played Gothic II there is almost 30 hours (!) of additional content, including a new land, expanded dialog of well-known characters, new items, new spells, improved visuals... and tougher gameplay to keep it a challenge, certainly worth the price.
The bad... you can't use old saves, you must start a new games, still, so much is new and fresh from the older version, starting over is a joy.
Replay value is very high, so many choices for characters, friends, enemies and career paths that each game will be a challenge and does not get old or typical.
So, for less than 20 bucks you can get about 150 hours (or more) of quality gameplay, a bargain for sure.
