ArbitraryWater: Arena is a curiosity at best. It's neat to see where The Elder Scrolls series got its start, but it's never had my interest long enough for me to get anywhere in that game.
Daggerfall, on the other hand, is sort of a beautiful mess and well worth taking a look at. Not because it's the great Ur-CRPG some would have you believe, but its scope and ambition is still impressive to this day even if half of it is still broken. It's a massive sandbox-y open world filled to the brim with procedurally generated insanity, be it the eerily empty countryside or the confusingly labyrinthine dungeons. It's worth looking at for a couple of hours at least.
Greywolf1: Which half of Daggerfall is broken? And have you been curious enough when playing Arena?
"Curious enough"? Is that meant to be condescending? Arena is interesting from a historical perspective, but what I played of it wasn't interesting enough for me to want to play more. It has the curse of being an early 3D game and controls pretty awkwardly. If I'm gonna play an old-school CRPG, I might as well stick to ones I find mechanically interesting.
The half of Daggerfall that is broken is that it's mechanically very easy to exploit. Some of the skills are worthless (The language skills, Streetwise/Etiquette), some are dubious (Lockpick is avoidable unless you want to join the thieves guild, since you can bash down doors with your fists to avoid damaging your weapons) and some are made invalid with spells (being able to jump and climb is nice, but a cheap levitation spell does the trick much better). And there's the part where it's janky as shit, even with all the bugs fixed. Procedurally generated quests from generic NPCs in procedurally generated towns sending you to procedurally generated dungeons that I've heard described as "mating octopi" in search of a procedurally generated quest objective that might've been placed in an area that is impossible to reach, or maybe it just clips through the wall! Don't get me wrong, I like Daggerfall
because it's crazy, but it makes Morrowind look straightforward and accessible by comparison.
