RuneScape

RuneScape endures as the longest-running free-to-play MMORPG, with Jagex's 2001 browser classic attracting over 200 million accounts and its Old School version hitting 150,000 concurrent players in 2023—faster than the average MMO's post-launch retention by 40%. The game's 28 skill system offers unmatched progression depth, though its point-and-click interface lags behind #6 Black Desert Online's action combat. A 3.9/5 player rating across 50,000 reviews reflects dated graphics, but its $115 million annual revenue proves the subscription-based model still works. RuneScape's longevity outperforms #9 Guild Wars 2's declining player base, making it the definitive gateway MMO.
