Morrowind:
Terrible textures
Terrible animations
Bad magic effects
No real mountains
No snow or any dynamic weather effects
No dynamic speed tree technology
LOTS of identical looking external towns and villages (same textures, etc)
No dynamic traps
Dungeons are static with lots of reused textures and conventions
Year 2002. Average gaming PC was some Pentium3 celeron, 64 MB ram and Geforce2 card.
About 400(without expansions)
No built-in house ownership
You can't buy a house, but you can get it by different means.
No comment
Main story-line is pretty boring and can be super short if desired
Some location markers appear on map after talking to NPCs which can't be disabled
Boring quests
As opposed to Skyrim?
Compared to what exactly? Other TES games? Seriously? For a lot of quests, you had different choices, in Skyrim you have one option almost all the time.
