Old school.
Quests, actual long, challenging, well-made quests. Fun minigames that you can play with friends, to receive items that can aide you in bossing, and not just end tier gear.
No, I enjoy remakes; just sucks there is not many out there that are old school anymore.
It started dying when RS released Oldschool, but i dont think it'll completely die out for a LONG time, there will always be RSPS.
