Translation of OP: Why do all RPGs seem to take place in a time period between 300 AD and thousands of years in the future?
You know, I don't know. But when I think about it that way, it doesn't seem like a big deal at all.
But I digress. It am getting pretty bored of the following three settings:
Tolkein rip-offs (e.g. Elder Scrolls, Fable)
Star Trek/Wars rip-offs (e.g. Mass Effect)
Post-apocalyptic wasteland (e.g. Fallout 3, Borderlands)
If you're bothered I only listed WRPGs as examples, well qq. It's one their biggest faults: uninspired settings. JRPGs may have cooky characters and goofy outfits, but I'll be darned if their settings aren't dazzling.
As for settings I'd like to see done proper? Steam punk. And I don't mean the way the Japanese do it (which is pretty darned cool). But straight up Jules Verne / H.G. Wells / Mark Twain sort of thing. You know, like Arcanum.
