Oh yeah, the economy. After the first few levels there’s no point in worrying about wealth for many, many reasons even if you go out of your way to avoid selling homemade potions to vendor scamps and mudcrabs.
Enchanted weapons and other charged items means taking at least half a minute for several castings of Soultrap 5 seconds on Target + Summon Golden Saint for 5 seconds on Self, each followed by beatsticking and navigating the idiot interface to recharge each and every time… instead of just a momentary click of your hot-key’d magicka potion. By the way 1/4 the time you cast your Soultrap/Saint spell will crash to desktop.
There aren’t enough hotkeys, especially as a mage, so you never use 90% of your spells because it’s too much of a time-wasting drag to stop combat and select a spell and go back every single time as if spellcasting weren’t enough of a time-wasting drag to begin with.
The enemies are boring and stop being a threat after four hours of grinding (or eight hours for Mournhold, or twelve hours for Solstheim) even with both the difficulty slider at +100 and ‘sandbagging’ by sticking with crap equipment and/or spells which makes no in-character sense unless you’re roleplaying a masochist, moron, and/or cultist of Sheogorath (but see below).
By the way, intentionally gimping yourself for the sake of making things more fun and interesting, is neither fun nor interesting, for anyone. We all know what you’re doing, it isn’t fooling anyone (especially not yourself) no matter how long and twisted your mental gymnastics in denial and justification, so keep your “waah badwrongfun / ROLEplayers-not-ROLLplayers / stormwind fallacy” etc. to yourself.
Anyway, we can go all day listing post-crash fixes, balancers, silly & illogical meta-gaming and so forth. And every single thing you apply is yet another mod which means yet another ball for Morrowind to struggle juggling.
Then after all that, if you’ve already “done it all” and want more quests, enemies, gameplay options (try and be a people-hating, self-sufficient, au naturel herbalist and craftsman without mods), and so forth, guess what? Every new mod is more crashing when even code-patched Morrowind struggles to keep each new ball a’juggle! And don’t give me Tamriel Rebuilt, which means you don’t get to play with almost any of those spiffy monster (aside from default), NPC, weapon, and texture/etc mods unless you want to spend 80 hours in the Construction Set modding TR yourself!
THEN after all THAT, if you attend to the most “optional” route because you can’t stand how ugly Morrowind is even by early-00’s standards, from the monsters to the outfits to your weapons and every spell: not only does each new mod and texture-replacement spell even more crashing a’top the prior piles, now you get to deal with insane as even today’s high-end PCs can barely handle all the bloom, HDR, infinite view distances, 16384×16384 textures, bump maps, and particles on an engine not designed to handle it as most of those technologies didn’t exist back then so of course the already half-broken engine isn’t optimized for any of it.
Morrowind is lovely but to make it no longer boring, unbalanced, illogical (by itself, and what you must do in the meta-game to not break everything even if it would make perfect sense in-character do do so — in real life, if facing a life-or-death situation, would you rather the best equipment you can get your hands on or would you leave it behind and keep your dull knife and rusty tin suit?), and ugly, if you’ve already “done it all” a dozen times with every imaginable character type with every race/gender, none of it is worth the resultant bugginess far beyond its original, half-broke state.
