"This is probably my main problem with tes lore, it draws so heavily from roman, scandinavian, japanese and other cultures sometimes that I get kinda turned off."
I'm the opposite. That's what I love about tes. When I first played morrowind I expected imperials to be based off typical medieval british culture like most western rpgs, but it was refreshing to see inspiration from imperial rome instead. Besides, I don't think they borrowed heavily, just seems inspired not 'ripping off'
Yeah well, I'm no fan of the medieval british culture in fantasy either. in my opinion when creating a world it is important to create from scratch, if I want a civilization I'd start with writing key questions.
For example: how does their infrastructure look, why does it look like this and so on? I try to come up with something that feels good and is believeable, that I think is cool and then I just go from question to question,
I look at how the different answers work with eachother and how this system would work with that religion and so on, I'm inevitably drawing inspiration from real world stuff but I can make the reader feel like it's completely unique(if i'm good). Sometimes it just feels that bethesda adds already existing finnished templates, put them together and make their own story based upon them. And I'm personally not a fan of that.
Then again it's probably better for the mainstream audience as it is easier to relate, and I do like a lot of the lore, especially the dunmer lore. But yeah... I probably made little sense.
