Forget butterfly clips, trucker caps, and flip phones: nothing screams the early 2000s like a Neopets or RuneScape-style online PC game. Growing up in the 2000s, the free-to-play landscape was immensely different. Hundreds of thousands of Flash games were available for free online, from the fan-made to the corporate promotional. Mostly short and sweet, these games could run even on a lower-end PC. Microtransactions were nearly unheard of, and many made games for the simple joy of creation (and a healthy dose of ad revenue). They weren’t always good, but they were usually free.
