Might come back to RS soon. With that being said, RS3 looks too confusing and I'm not sure if OSRS has enough content to make it worth playing regularly.
RS3 is pay to win shite, OSRS is definitely worth playing, would recommend starting as an Ironman, you can't trade with anyone so have to gather all your own Drops and Supplies.
Makes even easy drops seem big, and rune items so much more rewarding
Hey, I quit RS back in 2011 and just came back not too long ago. They've made quite a bit of updates for OSRS in the past few years and the updates are usually decided by polls from players so don't worry about them messing the game up again. While the playerbase isn't as active as the prime time of RS, it's still pretty active with size of playerbase just behind WoW.
Also, OSRS mobile is coming out soon so it might bring back some players. I would suggest you to give it a shot.
Recently got back into it after quitting for awhile.. Have been playing this game on and off for like 10+ years. Can't seem to quit altogether due to nostalgia reasons.
Came back to OSRS during the summer. Was fun for a bit, but definitely lost motivation to grind especially since I prefer PvP content (I can't be bothered grinding 80+ combat stats). The nostalgic feeling wore off pretty quick for me. I'm sure I'll be back months down the road, but for now I think I'm done with OSRS for a bit.
Tbh either is worth playing if u find a good community, example, Im in dungeoneering, or was (not sommuch anymore) l, and barbarian assault for oldschool
OSRS doesn't really have much end-game content that will keep you motivated to play past a certain point IMO. The grind to get there was enjoyable for me though.
