Elder Scrolls and FO3/NV are at the core of what it means to have an open world RPG: it's about seeing what's out there, picking a task for yourself and doing it or getting lost along the way. There's enough gameplay depth to keep it interesting but people asking for Monster Hunter/Souls-like combat are really missing the point, it's not remotely the same type of core game loop.
RPGs in general used to be quite like this (think Early EQ for one example) but over time that term "RPG" got turned into meaning fantasy world where you go from one quest hub to the next to work on shopping list quests. I still don't know why no other developer has jumped into this market that Bethesda has let languish (Skyrim is 14 years old at this point)
As an aside, moving objects around with somewhat realistic physics was quite the novelty at the time Oblivion came out. People where ooh'ing and aah'ing over being able to move the hanging chains in the prison cell around.
heres a terrible video by a moron on the matter:
It is an interesting question. and there are SOME options.
mods, indie, aa/aaa?
enderal is a gothic-like in skyrim engine, as he actually notes.
and really many of the contenders could be called that.
tainted grail is the next big option.but much lower budget
ardenfall is an indie title trying to recreate morrowind/skyrim.
avowed was stealing the LOOK, but clearly was not a TES like.
What is a TESlike in the first place? ultima underworld+might and magic.
The new term people have started to come up with is "immersive fantasy life sim"
this is not PS's best video. its long and rambling. but the "immersive fantasy life sim' idea, is something he gets into here somewhere.. I forget the time stamp.
Which is where I make my point.
what else could be described as "immersive fantasy life sims'?
what did skyrim, and fallout 4 both add? home/base building and survival mode.
fallout 4 was considered for the longest time the best and deepest survival base builder. out conan exiling, conan exiles, valhiem,etc.
conan exiles, enshrouded share a TON of dna with TES games. everything but civilization and quests via that. they are basically TES games, in a wilderness with no cities.
those two especially have similar world design, with points of interest, dungeons, etc. even some civilization with "quests". added the "living" settlements has helped alot.
things like Valhiem are far more proc gen, and don't really have the same dungeons/poi, etc as conan/enshrouded with their hand crafted worlds. Although, enshrouded actually used proc gen to form the world, and then it was hand touched up on. same way tes games worlds were crafted. dunno if proc gen was used in conan. its so big, its likely?
imagine if conan exiles let you actually talk to the humanoid npcs. added faction rep, and crime, etc. it would 100% just be a tes game.
