Hawk52: Being someone who got sucked into buying the Gothic games based on all the talk on these forums when it was on sale last year:
Do not do it. I repeat: Do not do it.
Gothic 2 has never ran for me on Steam. At all. Period. Never. Zip. I think I got to the title screen once, and then it crashed. I've never gotten back to it again.
Gothic 3 does not deserve to be paid for or pirated. It is a completely broken game from every single aspect possible for a game. It doesn't correctly work on ANY level. Even with the fan patch, it doesn't change many fundamental flaws in the game. Specifically the "feel" of the game. When you strike an enemy, you should have some type of registry of the hit. I never got that in Gothic. It's like a detached floating feeling. It also doesn't run well even with the latest fan patches. The game engine is completely broken inherently.
Maybe if you can look past all these flaws, be willing to invest time to learn the system and fan patch the game you might find something. Or you could just buy an RPG from a developer who doesn't fail at their job and cut out all the middle man.
Gothic I and II are classics. Gothic was the FIRST rpg that had a more involved AI in an open world setting that actually did things rather then "stand here and wait for person x to talk to you..
gothic II was even better then the first, taking the series a step further in the genre.
Gothic III is a game that wasn't finished, the original developers from gothic were rushed getting it out and afterwards split with the publisher and lost the rights to use the Gothic name (as the publisher, not the developer) owned it. So they went and developed Risen whcih was also a good open world rpg in a similar sense to the Gothic games and has a sequel on the way.
Gothic I and II I recommend to ANY rpg fans who understand that they are older games, they don't look good compared to todays games and are rough around the edges in terms of controls and functions. It takes time to get used to it all but once you do underneath it is a great rpg series that is unique in itself and has depth that you don't get much even compared to the Elder Scrolls series.
