I agree with OP, the name isn't bad, but could be better.
It's rarely, if ever, marketed as Elder Scrolls. Elder Scrolls Online is the only one that comes to mind and that hasn't been a great success. The great successes of that series were marketed with stronger names like Morrowwind, Oblivion, and Skyrim.
It's not too late. Retro Pixel Castles changed its name to Rise to Ruins during early access, but after being released on Steam. Will it suffer from a loss of name recognition? That remains to be seen. Either way, it's definitely not impossible.
