The Elder Scrolls Online will be joining another big MMORPG release on PlayStation 4 that actually won't require PlayStation Plus membership to play, despite online multiplayer typically being a service limited to Plus level access on the PS4. Yet exceptions are not limited to F2P titles like DCU Online and Warframe, as both Final Fantasy XIV and TESO already require their own subscription fees ($14.99/£8.99/€12.99 in TESO's case).
ZeniMax Online Studios was able to confirm on the official PlayStation blog that their monthly subscription fee will be all you need to pay in order to play, even if you aren't entitled to online multiplayer on the PS4 because you don't have PS Plus membership. Sadly a similar arrangement does not currently appear to be the case for the Xbox One version, as Bethesda confirms to Forbes that Xbox Live Gold membership will still be needed for players on Microsoft's platform.
With TESO hitting the PlayStation 4 and Xbox One a few months after it goes live on PC and Mac, ZeniMax saw fit to separate the console "megaservers" from those used by PC and Mac players. This means console players will be in worlds of their own, something ZeniMax deemed necessary due to how far behind they would be compared to the higher-level PC and Mac players come June. North American and European players will similarly not be sharing servers.
Unfortunately ZeniMax has yet to settle on a timeframe for a planned beta on PS4, so we'll need to stay tuned!
