You can still try the base game for free if you want to give it another go.
And when it goes on sale, the “Complete” Collection (First three expacs + the Living Story 2, 3, 4 and 5) is a steal at 50$/€. That’s 10 years of content you can catch up to. Even full price I’d say worth it, if you’re looking for a casual-friendly MMO with enough content to keep you entertained for a long time.
Another rec for GW2. I’d recommend you try the F2P game so you get a general sense of the mechanics and see if you like it, then wait for a sale to buy the “Elder Dragon Saga—Complete Collection” for half-price. I mean, there’s enough content for it to be worth 100 bucks, but for 50 it’s a bargain.
