I love role-playing games but couldn't never play wow because I only had a ps4 now I got a pc that will arrive in a few days and wow will be the first game I'll get but I don't have a clue about the whole versions etc how should I start now? Any tips would be good
There are two versions of WoW in principle.
Once the normal WoW aka »WoW Retail« and once »WoW Classic«.
With the purchase of Spielzeit (https://eu.shop.battle.net/de-de/product/world-of-warcraft-subscription or https://eu.shop.battle.net/de-de/product/world-of-warcraft-game-time) you have access to both versions.
»WoW Retail« is expanded regularly (approx. Every 2 years) with new chargeable extensions. All old expansions are part of the base game, i.e. Included in the game time.
Only the latest expansion, currently »https://eu.shop.battle.net/de-de/product/world-of-warcraft-shadowlands«, has to be bought separately if you want to play its content.
»WoW Retail« is more beginner-friendly, as there have been many improvements over the years.
"WoW Classic" is the version of WoW before the first expansion, or a variant with only the first expansion will appear soon. But you don't have to buy the extension here.
That's how it is.
