Titanium: You get used to both in about half an hour. By the early middle of the game, you're asking yourself "Clunky controls? What clunky controls?".
...
Kunovski: sorry, but not true... I've finished Gothic 2 quite without problems (controls were great) and I wanted to complete my experience of this universe by playing Gothic 1. but had to stop playing... I got involved in a first fight with a snapper, but the character was not able to strafe around a locked enemy, he jumped left and right instead while always loosing the focus. I've triple-checked the control settings but it was all correct (and the same as my settings in Gothic 2).
I finished G1 multiple times with no problems, controls were great. I guess you just have to get used to them or give up.
Wait, let me check something... I'll go reinstall it just to make sure.
There, just tried it, strafes just fine. Assign keys "q" and "e" for look left and right and assign keys "a" and "d" for strafe left and right. Look at an opponent and press a or d to circle around him. Hold action key and a w d to strike.
