I believe if Gothic 1 was a bit longer and bigger, it could replace Gothic 2 and become my most favorite game ever. ( Although it's still among the top 10. ) Because it had a better story background and atmosphere. I remember when I was playing it, it was the single thing that I was thinking about it. It was so engaging and addicting.
I had so much difficulty with the controls and performing simple tasks such as transferring loot from chests to my inventory, etc., that I had to throw in the towel on this game after a few hours.
Controls might sound extremely weird and uncomfortable at first, but you'll get used to it in no time. Actually I chose Gothic 1's control scheme when I was playing Gothic 2.
