half these bugs are features, like embarking on a large enough area to go past 2gb... sheesh your not running this game on CERNS computers are you?
I listed only bugs open on the bugtracker. And your example is wrong, maybe it can pass as "known limitation" but not as a feature.
Well, can't speak for Toady, but designed in limitations can be features. Take TES games, every man and his dog have modded in higher resolution world maps and models to every game since Morrowind, so why haven't Bethesda included them in the game? Because they have to provide a product that is going to run and look acceptable on 99% of their customer's computers, not cater to the minority who can run such things. Or, looking at it the other way, if they shipped Skyrim with high-res textures a whole bunch of people would be miffed their computer can't run the most beautiful version of the game, so they
release it separately. Thinking about your audience = design feature, not a bug.
Things like "Siegers waiting by bodies of dead leaders", "Turtles went extinct on my map (applies to all aquatic vermin)" and "Sewers inhabitants hanging out underwater near outflows" (but "(some of them stuck to walls)" is a clear bug) may pass as strange features but I see nothing more like this.
All of the siege related bugs can be, IMO, written off as part of the (long awaited) siege rewrite. All of the city/economic bugs can be written off as part of the (hopefully upcoming!) schedule and caravan part of the caravan-arc. In other words, we know that Toady has planned to address these things and shall be doing so in time; since it seems unlikely he'll deal with such bugs individually or on an ad-hoc basis, wouldn't it be better to take them off the list and wait for said rewrites to happen?
