Free Form play. The Best and most immersive RPG I have played to date, including oblivion. Exotic and atmospheric.
There are hundreds, if not thousands, of mods out there for this that are amazing and will improve overall graphics, npc faces and bodies, weather, quest fixes, insert additional quests/npcs/landmasses, etc.
Seriously get some mods and give yourself a private island estate or two, and maybe a private haunted castle in balmora. In fact while you are at it why not add dogs to morrowind’s cities, make the girls easier to look at, and add some new weather modes and durations.
Also at some point try being a thief, or at least stealing some: it is a blast. Go swipe the seyda neen tax and excise office warehouse key when you are starting out, this will give you taste of how fun sneaking can be.
I am going to make myself start a new game this summer and actually try to beat the game and not get distracted. This will be the fifth time I have tried this…
Only complaint: the journal sucks in this game. Oblivion fixed it nicely.
