There’s an exception to this, namely:
- online digital content, if you have already started downloading or streaming it and you agreed that you would lose your right of withdrawal by starting the performance.
Which is a standard game store industry tickbox or informed consent before purchase. After that. you can only appeal to the voluntarily refund policy of the game store.
That would be a legal question, that doesn’t cover the purchase portion.
The exact EULA says that by buying the game it is delivered “as is” and “as available”. Technically, access is granted through gametime to all versions of the game up to your content expansion level.
Changes are always made to the game, but this was highly unexpected.
This is actually Section 1.E.iii, as Section 7 is “Indemnity”. E.i and E.ii also states from the same subarticles:
E. Alterations to the Platform
i. Patches and Updates: Blizzard may update the Platform or part of the Platform, including Games, in order to, for example, without limitation:
2. perform temporary maintenance, fix bugs, implement technical adjustments, and make improvements;
3. update or upgrade the Platform including updating the structure, design, or layout of the Platform;
4. balance, improve, update, or renew a Game;
5. ensure the security of the Platform; and
6. to combat illegal and/or harmful activities and the use of unauthorized programs or other activities which breach this Agreement.
And E.ii
ii. Unless otherwise required by applicable laws and provided that any such updates do not result in material derogation in the functionality of the Platform:
- You hereby grant to Blizzard consent to deploy and apply such patches, updates, and modifications; and
- We may update the Platform remotely without notifying you.
Should you feel that you want a (partial) refund because of security updates to the game to combat botters as many demands Blizzard to do so in the Classic games, you may open a ticket and enter in discussion to terminate your agreement with Blizzard.
