We’ll kick things off with an oldie, but a goodie. Ragnarok Online has been around forever. Well, not forever, but certainly for a good amount of time. It launched in 2002 in Korea and is still going strong. Your character grows and changes. The world grows and changes. It still gets regular updates and remains relevant, and you might even be able to use this opportunity to reunite with old friends. This free MMORPG is available on PCs.
