I started my PC gaming experience with LEGO Universe, an MMO with a free to play section but most of the content was behind monthly passes. I could never convince my parents to buy me the passes, and they shut down the servers relatively soon after I started playing. But I have great memories of it and still yearn to explore those worlds behind the pay wall to this day.
Thanks! Currently I don’t have time at all, but maybe I will remember this one day and come back to it.
