O Big Bang

“Great idle game channeling OG RuneScape with natural skill progression, engaging quests, and permanent shop upgrades for smoother automation. Features dungeons with chest drops, cross-platform play, and frequent weekly updates. While visual assets use AI and the wiki can be incomplete, it's a stellar experience even for non-idle fans.”
