TTRPG进化报告提示词

i need a report on evolution in TTRPGs, especially the major families of rules that have evolved over the past few years, and the emblematic games of each. make it an interesting read with examples of gameplay mechanics. start with the 1970s but focus most on post 20102. all genres, all types, no need for a chart unless it helps, but good narratives with sections contrasting examples of how the game might actually play. maybe the same sort of gameplay challenge under different mechanics?
