“The Premium Bundle includes the following content: • ELDEN RING Shadow of the Erdtree expansion • ELDEN RING Shadow of the Erdtree Digital Artbook & Original Soundtrack”
Now I don’t know about you, but I’m sure I can live with the artbook and soundtrack being put behind a £5 price tag.
I can’t do much to answer your original question but you could always try it and refund it within the 2 hour period steam allows.
Sure, you won’t be able to get the full experience but in that time you should be able to get a basic feel for the game and some characters which could let you form your own opinion.
