So the sequels make the necessary changes that you desire…and you won't play them because of issues in the first game - issues that were addressed? That line of thinking really doesn't make much sense

. Reading your largest complaint - that the player can get by through the usage of combat instead of pure stealth, where the player is "punished" if they are detected by making combat really risky - I strongly recommend the sequels. I haven't played Thief 2 in ages, but I played Deadly Shadows within the past few years and unless I was doing something wrong after being detected, direct combat was
not a good idea. It seems to have been designed in a manner where if the player is engaging more than 1 opponent at a time, they will lose - and even single combat is very risky.
