Archangel... I still have the box right here. I thought it was absolutely silly as a kid and stopped playing at the part in Berlin. At that point you get guns and the gunplay is horrible. You can't hit enemies that are too close, because the bullets appear behind them then. Other than that I only remeber that it was a very tedious but not very difficult game with horrible voiceacting and a bland story.
Arx Fatalis is on GOG too and runs fine. It's a decent game with some flaws. The magic system is a bit of a pain as it only works when you are very accurate with drawing the runes. It's also very linear, but it doesn't tell you that! You are absolutely able to do quests in the wrong order and end up at a dead end after multiple hours of playing. This doesn't mean you have to restart the game, though - but you may be forced to walk all the way back almost to the start and later back again.
